With just about everyone using a smart phone, it is important for mobile apps to have beautifully designed icons to represent the brand. In this tutorial, we will show you how to create a beautiful 3D starfish icon using several applications including Photoshop, Cinema 4D, and ZBrush. In the process we will show you how to create 3D objects and then combine them with textures in Photoshop to create an amazing icon. Let's get started!


Tutorial Assets

To complete the tutorial you will need the following assets.


1. Modeling the icon border

Step 1

It's important that you have some knowledge of Cinema 4D to complete this tutorial. Open Cinema 4D and create a Rectangle Object (Create > Spline > Rectangle) or use the shortcut bar as shown below.

Shortcut Bar

Step 2

Keep the rectangle selected and edit the object properties on the Attributes Manager, set width and height to 36cm, turn on the Rounding option and set the value to 6cm. For some unknown reason the pixel unit was removed from Cinema 4D, these values represents the approximate ratio of a 1024x1024 pixels icon.

Attributes Manager

Step 3

To create depth to your rectangle use the shortcut bar and select Extrude Nurbs, go to the Object Manager panel and drag the rectangle inside the Extrude Nurbs object. To edit the depth of the shape, select the object and set the Movement on the Z axis to 5cm in the Attributes Manager as shown below.

Extrude Nurbs

Step 4

Now it's time to convert your model into a polygonal object, choose Mesh > Conversion > Make Editable. After that you'll see a different object in the Object Manager, expand Extrude Nurbs and delete the Cap 1 and Cap 2.

Make Editable

Step 5

Extrusion is one of the most important tasks in 3D modeling and you will use it to create the border. Select your object, choose the Edge mode and go to menu Select > Loop Selection. Pass your mouse over the polygon until the edge is highlighted, then click on it. Ensure that a yellow highlight is over the edge, right-click and choose Extrude from the menu. Press T (Scale Tool) and hold Command/Ctrl while dragging to the center of the object, you'll notice a new face moving from the edge, set the size of X and Y on the Coordinates panel to 28cm.

Extrude

Step 6

Keep the edge highlighted and repeat the last step to extrude it again, but instead of use T press E (Move Tool) and hold Command/Ctrl while dragging the Z arrow (Blue) to the left. Set the precise position on the Coordinates panel, use 0cm on the Z axis.

Extrude inside

Step 7

Symmetry is a very useful tool, use it to close the object. Choose Create > Modeling > Symmetry, got to the Object Manager and drag your object inside Symmetry. Select Symmetry from the Object Manager and set the Mirror Plane to XY on the Attributes Manager.

Symmetry

Step 8

Time to make your object editable again, choose Mesh > Conversion > Make Editable, the result is a group with the name Symmetry. On the Object Manager drag Extrude Nurbs outside the group and delete Symmetry. Double click Extrude Nurbs and rename it to Icon Shape, hit enter to confirm.

You don't need the extra edge that appeared with the symmetry step, so let's remove it. Turn Edge mode on and use Loop Selection to select the middle edge, but in this case hold shift to grab the inner edge as well. Right click on any of the highlighted edges and choose Dissolve from the context menu. It's gone!

Dissolve

Step 9

Next you'll apply a small bevel on the edges. Keep Edge mode on, get Loop Selection tool to grab all four external edges, right click and choose Bevel. Don't do anything on the view port, instead use the Attributes Manager to apply the same settings to all edges. Type 0.1cm to Inner Offset and add 1 Subdivision, hit Apply to confirm, the edge will be subdivided into three.

Bevel

Step 10

The icon border is ready to sculpt, you need to export it using a format compatible with ZBrush, go to File > Export > Wafefront (*.obj) select the path you want to store the file and hit Save. Save your project and close Cinema 4D. Well done!

Export

2. Sculpting in ZBrush

Step 1

I think that work with ZBrush requires more artistic abilities than technical knowledge, that's why you don't need to worry if you achieve different results.

Open ZBrush and import the OBJ file you have created with Cinema4D, use the menu located at the right side of the interface. The object you have created will appear right below as a tool.

Import

Step 2

Draw on the stage and you'll see the object you have created. Don't worry about size or position, just release the shape. Enter Edit Mode (T) and experiment the manipulation commands:

  • Rotate: Click outside the object
  • Move: Alt+Click outside the object
  • Zoom: Alt+Click outside the object then release Alt

Before you start sculpting, it's necessary to add resolution to your object, press Command/Ctrl+D five times till the Mesh gets more than 500.000 points. The more you add the more detail you can have, but it will make your computer work very slow.

Placing Object

Step 3

Experiment drawing on the object you will notice deformations on the surface. While sculpting you need to know 2 simple things, hold ALT to invert the brush effect or hold SHIFT to smooth the effect. The Standard brush is the best for this kind of organic shape.

To control brush size and strength, press S for Draw Size and O for Focal Shift, you'll use it a lot.

Placing Object

Step 4

Don't use brush on the outside faces, concentrate the details inside.

Outside Border

Step 5

You can undo your steps if there is something you don't like, but ZBrush workflow is very peculiar. Sometimes the best option is to create a new document and start it again.

At this point, you should exercise your faith and trust that your object will become water soon, it depends on the material we'll use. Create soft deformations, don't apply to much strength with the brush. At the end you should get something similar as shown below.

Sculpt Tips

Step 6

You need to return to Cinema 4D to continue the magic, but before add more geometry to the object, press Command/Ctrl + D and look at the control bar located below the main menu, if you got more than 3 million points it's a good time to stop adding geometry.

Adding Geometry

Step 7

Now you need to do a simple trick to reduce the number of points without affecting mesh quality. Go to Zplugin > Decimation Master configure the percentage of decimation to 5%, click on Pre-Process All and wait for ZBrush to finish the calculations. When the process is finished go to the same menu and now click on Decimate All, it will reduce the poly count of your object.

Decimate

Step 8

Export your model using the Tool menu on the right and use the OBJ format.

Exporting

3. Simulating realistic water

Step 1

Return to Cinema 4D go to File > Open and open the file you have created with ZBrush. Use Object Manager to rename it to Icon Shape. Make sure X and Y axis sizes are 36cm, also set Y position to 18cm.

Opening the file

Step 2

You need to create an infinite plane to place your icon, go to Create > Object > Plane, in the Attributes Manager set the Width and Height to 400cm and the Width and Height Segments to 5, use Coordinate Manager set the Z position to 100cm.

Infinite background

Step 3

Deform the plane, choose Create > Deformer > Bend. In the Object Manager drag Bend inside the Plane. Edit the fields in the Attribute Manager and Coordinate Manager exactly as shown below.

Bend Deformer

Step 4

Smooth the plane using a HyperNURBS object, go to Create > Nurbs > HyperNURBS, drag the Plane inside the HyperNURBS in the Object Manager.

To finish your plane apply a material to give color to it, go to Create > Material > New Material. The material attributes appears in the Attributes Manager, edit the color values to create a blue color (R:50 G:195 B255) and drag the Blue Ball over the plane on the view port to see the result. Rename your material in the Material panel located on the bottom left of the interface, double click the sphere name and type Plane.

Bend Deformer
Material Editor

Step 5

In this step you will create the water material, go to Create > Material > New Material and rename it to Water. Double click the gray sphere to open the Material Editor window and follow the images below to properly configure it. When finished drag the material upon the Icon Shape object in the view port.

Material Editor Specular
Object with material

Step 6

Go to Create > Light > Light to insert a light source on your scene, rename to Left Light and set the position, type -80cm for X axis and 25cm for Y axis.

Configure light properties in the Attributes Manager, choose the General tab, set Intensity to 50% and color to R220 G240 B255. In the Shadow tab select Shadow Maps (Soft) from the drop down menu, set intensity to 200% and Shadow Map to 1000x1000.

Light coordinates
Light general
Light shadow

Step 7

Select Left Light, copy and paste it and rename to Right Light in the Object Manager. Use Coordinate panel to position the new light to the right of the icon, change the X axis to 80cm. Edit Intensity value to 70% in the General tab in the Attribute Manager.

Duplicate Light

Step 8

Create a SKY to compose the scene. Go to Create > Environment > Sky, apply a new material to the object with the following color settings:

  • R:200
  • G:235
  • B:255

You can drag the material sphere from Material Manager and release over the Sky object in the Object Manager. You should see a small sphere connected to the object as shown below.

Sky

Step 9

Create some bubbles to make the water more believable, choose Create > Object > Sphere, set Radius 2cm and Segments 24, rename the object to Bubble 1. To have a better view of the object adjust the coordinates to 0cm on X axis, 10cm on Y axis and -30cm on Z axis.

Go to Mesh > Conversion > Make Editable and press T to edit the size. In the view port grab the green manipulator to resize the object on the Y axis and drag to reach 6cm, it will appear more oval. Apply the Water material to the bubble dragging it over the object.

Create a Bubble

Step 10

Add deformation to the bubble, go to Create > Deformer > Twist, set the position of the object to 10cm on Y axis, -30cm on Z axis and rotate 45 degrees on the B axis using the Coordinate Manager. Drop Twist inside Bubble 1 in the Object Manager, configure it as shown below using the Attribute Manager.

Deforming the Bubble

Step 11

At this points it's a good idea organize the Object Manager, Shift click the following objects:

  • Sky
  • Right Line
  • Left Line
  • HyperNURBS

In the Object Manager, click with right mouse button on any of the objects you have selected then choose Group Objects from the context menu. Double click Null group and rename it to Scene.

Organize Object Manager
Rename Group

Step 12

Duplicate Bubble 1 by pressing Command/Ctrl + C and Command/Ctrl + V then press E (Move Tool) to drag the new bubble away from Bubble 1, the position is not important right now. Rename the duplicate to Bubble 2.

Duplicate Bubble

Step 13

Select Bubble 2, use the Coordinate Manager to change Y size from 6cm to 3cm, you'll notice a change in the shape. Expand the hierarchy in the Object Manager and select the Twist deformer. Alter the Angle entry in the Attribute Manager to 120º, go to the Coordinate Manager and change B Rotation to 135º.

Deform Bubble

Step 14

Repeat Steps 12 and 13 at least 4 times to create 6 different bubbles, no problems if you want more. Experiment different sizes and rotations to achieve distinctive results.

Random Bubbles

Step 15

Before you begin positioning the bubbles use the sub-menu at the view port, as shown below to turn off the Deformer visibility.

Filter Menu

Step 16

Because we are dealing with a very complex mesh the placement of the bubbles requires the use of other cameras. Use the icon located at the right side of the view port sub-menu to change the layout.

Layout icon
Four cameras

Step 17

In the sub-menu of Top, Right and Front view choose Display > Gouraud Shading to change the preview mode.

Preview Mode

Step 18

Start with Front view, select each bubble press E (Move tool) and place at your own will, then press T (Size tool) adjust the size of the big bubbles to fit in the Icon Shape. There is no need to be precise here, the more random and casual the better.

Front View

Step 19

Change to Top view to place each bubble over the icon shape on the Z axis.

Top View

Step 20

Change the camera layout clicking on the icon at the perspective view. Group all the Bubbles and give the name Bubbles to the group.

Change camera layout

Step 10

Create an empty layer and name it Bright Soft Brush. Alt-drag the mask of layer Render and release over Bright Soft Brush, this will duplicate the mask. Grab a soft brush (size 300px), use white color and paint over the edges to make more bright, like an inner glow.

Bright Brush

Step 11

Create a new layer, name it Shadow and set blend mode to Multiply. Alt-drag the mask of layer Bright Soft Brush and release over Shadow. Use the same soft brush with a dark blue color R:75 G:120 B:155, paint the inner edge creating a soft shadow.

Shadow Brush

Step 12

Create a new layer and name it Specular. Press P to select Pen Tool, draw a few shapes and convert them to selection as shown below. Paint this selection with white color to create a specular light. Add Outer Glow effect using the Layer Style button situated on the foot of Layer panel.

Step 15

Duplicate Soft Shadow 1, rename to Soft Shadow 2 and set layer Opacity to 80%. Press Command/Ctrl + T and stretch the layer to the boundaries of document. Erase some parts using a soft brush to make it more natural.

Change layer size

Step 16

Import the Sand Texture to your document and label it Sand. Create a new group beneath Water Border, name it Sand and put the texture inside. Press CMD/CTRL + T and set the size to 200% in the Options bar. Don't worry with the resolution, in the next steps you'll work on that.

Import Sand Texture

Step 17

Select Rectangular Marquee Tool and do a square marquee to keep only the center of the texture. Mask Sand group with this selection.

Rectangular Marquee

Step 18

Repair the texture removing all the dirt, use Clone Stamp (S) with a soft brush. Remember to hold Alt to clone from clean areas.

Clone Stamp
Repaired Sand

Step 19

Continuing the process of repair the texture, create a new layer above Sand and fill it with a medium gray R:128 G:128 B:128 then go to Filter > Noise > Add Noise set the Amount to 12%, Uniform Distribution and Monochromatic. Change layer Blend mode to Overlay and label it Noise. This will add grain to your texture and ease the resolution problem.

Add Noise

Step 20

Finally apply a Smart Sharpen filter to Sand layer, set Amount to 160%, Radius 1,5px and check More Accurate.

Smart Sharpen

Step 21

Add 2 adjustment layers below Noise to regulate texture's colors, Brightness/Contrast and Color Balance.

Color Correction

Step 22

Create an empty layer above Noise, name it Soft Light and set Opacity to 50%. Use a soft brush(size 1300px) to draw a faded white light in the center of the sand texture.

Soft Light

Step 23

Add a new layer, name it Soft Shadow 1 and set Blend mode Overlay. Press B, select a soft brush (size 120px) with black color. Paint over the shadows that already exist to make them stronger.

Duplicate the layer, name it Soft Shadow 2, set Opacity to 50% and use Eraser (E) to delete some parts. Follow the images below to see what areas you need to paint.

Painting shadows

Step 24

Add another layer, label it Cast Shadow 1 and set Opacity 50%. Paint in black a subtle shadow as shown below.

Subtle Shadow

Step 25

Create a layer, name it Hard Shadow 1 set Opacity to 60% and Blend mode Color Burn. Press P for Pen Tool and draw a shape close to the edge. Command/Ctrl + Enter to transform into selection and fill it with a light blue R:144 G:184 B:214.

Hard Shadow

Step 26

Create a new layer, label it Hard Shadow 2, set Opacity to 40% and Blend mode Multiply. Repeat Step 25, but create a bigger shadow like the image below.

Big Hard Shadow

Step 27

Now you'll work on the starfish. Create a new layer between Water Border and Sand groups, rename it to Color. Fill a square on the center of the document with a dark red color R:125 G:5 B:15. Select new layer and press Command/Ctrl + G to create a group with the name Starfish.

Fill Layer

Step 28

Ensure layer Color is selected in the Layers panel, then use the Pen Tool (P) to draw a 5 point star with rounded corners, like the image below. Click with right mouse button and choose Create Vector Mask from the popup menu.

Vector Mask

Step 29

Now you have a flat star shape ready for paint. Create 2 empty layers above Color layer, name the first Soft Shadow 1 and the second Soft Light 1, select booth while holding Shift then press Command/Ctrl + ALT + G to make a Clipping Mask.

Flat Star Shape

Step 30

The following steps will test your brush skills, be patient and repeat until you get satisfied. Select Soft Shadow 1, set layer Opacity 60%. Pic a soft brush (Size 100px) with a dark red R:65 G:0 B:0. Paint gently defining shadow areas as shown below.

Painting Shadows

Step 31

Go for Soft Light 1, use the same brush, but now with a light red R:165 G:0 B:0. Same deal, smooth painting bright areas.

Painting Light

Step 32

Create a new layer, name it Texture 1 and make a clipping mask. Grab a small brush (size 5px) with hardness 50% and set an orange color R:230 G:135 B:0. Start painting the central lines of the texture, correct your lines using the Eraser (E) with the same brush settings.

Paint soft dark strokes around the lines to give depth to the texture. Use a soft brush with a dark red R:65 G:0 B:0. Don't be super precise, mistakes make the texture feels more organic and natural.

Lines Texture
Lines Texture

Step 33

Keep the workflow until you get a similar result as shown below. Experiment a soft brush to fade some lines with the Eraser (E). Don't worry if your lines get a dirty look, we will further soften this effect.

Lines Texture

Faded Lines
Lines Texture

Step 34

Intensify the texture, press Command/Ctrl + J to duplicate layer Texture 1, rename to Texture 2 Duplicated and set Opacity 50%.

Intensify texture

Step 35

Create a new clipped layer with the name Soft Light 2 and Blend mode Screen. Press B, choose a ragged brush (size 200px), set color to R:210 G:175 B:140, paint an additional light over the starfish.

Additional Light

Step 36

Create a new layer with the name Spores, it's not necessary to make a Clipping mask this time. Use an Elliptical Marquee to draw a circle with 30 x 30 pixels and fill it with a dark red R:115 G:10 B:10. Press Command/Ctrl + D to deselect. Lock transparent pixels to avoid painting outside the layer.

Spores Layer

Step 37

Set midtone color R:245 G:210 B:145, use a ragged brush(size 25px) and paint some bright areas, consider a light source coming from the upper right. Choose a highlight color R:245 G:210 B:145 and set brush opacity to 40%. Mix all the colors to create a sense of depth, experiment varied brush sizes.

Painting the Spore

Step 38

It'll be crazy to paint all the spores, so take advantage of copy and paste, change the size to make them different. Star by duplicating in the central circle of the star and place them on the line intersections. Don't create new layers, use only one layer, the Spores.

Duplicating the Spores

Step 39

To make the starfish more three-dimensional some perspective spores are necessary. Use the same process of steps 36 and 37. Draw a few and duplicate them using the same workflow of step 38. Use the lines to see where they should point, but again, don't be precise to make it natural.

Spores direction
Perspective Spores
Complete Spores

Step 40

The Spores needs to cast shadow to compose with the Starfish, unfortunately there isn't shortcut to do it. Create a new layer beneath Spores, name it Spores Cast Shadow 1. Press B and choose a ragged brush (size 10px) Opacity 60% and black color. Zoom in the image to paint the shadows, remember the light comes from the upper right corner.

Cast shadow

Step 41

Add inner shadow to the spores on the left. Create a new layer above Spores and make a Clipping mask. Name it Soft Shadow 1. Use a soft brush (Opacity 80%) and paint with a dark red R:100 G:0 B:0.

Spores soft shadow

Step 42

Go to Layers panel, hold Command/Ctrl and click on the vector mask of layer Colors, a selection will appear. Now hold Command/Ctrl + Shift and click over the layer Spores it will add the spores shape to the selection.

Selection

Step 43

Use the active selection to Mask a new layer. Paint the layer with a soft light orange R:240 G:170 B:95.

Light painting

Step 44

Add a final light to the Starfish. Use again the mask you have created and place it on a new layer. Paint a white light using a big soft brush(Opacity 40%).

Soft Light painting

Step 45

In the next step you'll reduce the dirt of your brushes using a texture. Get the file Water Texture and place as the top layer of Starfish group, duplicate the layer pressing Command/Ctrl + J.

Water Texture

Step 46

Select the original layer, go to Edit > Transform > Flip Vertical. Mirror the images and merge booth layers naming it to Texture 2 as shown below.

Water Texture

Step 47

Press Command/Ctrl + SHIFT + U to Desaturate the texture, next increase Shadow values to 100 in Levels (Command/Ctrl + L). Set Opacity to 50% and Blend mode to Soft Light.

Water Texture

Step 48

Reduce texture size to 80% (Command/Ctrl + T), and apply a Smart Sharpen filter to it, Amount 100%, Radius 1px and check More Accurate.

Mask your layer, ensure Texture is selected in Layers panel. Hold Command/Ctrl and click on the Soft Light 4 mask to create a selection, then click Add Layer Mask button at the foot of Layers panel.

Water Texture

Step 49

Now project some shadows on the sand, start creating a layer below Color layer and name it Cast Shadow 1. Command/Ctrl click on the mask shape of Color layer to create a selection and fill with black color. Go to Filter > Blur > Motion Blur set Angle 60º and Distance 200 pixels. Erase unnecessary parts as shown below.

Motion Blur
Final touch

Step 50

Add a new layer and strengthen the shadows close to the Starfish edge. Set layer opacity to 50% and name it Cast Shadow 2. Use a soft brush with black color.

Shadow Strengthen

Step 51

Close Starfish group and leave it for a while, now we need to paint the seaweed. Use the Pent Tool (P) to create a new shape at the left of Starfish.

Seaweed Shape

Step 52

Create a vector mask using the active path on a new layer, store inside a new group between Water Border and Starfish. Fill the layer with the following color R:85 G:100 B:55.

Seaweed Layer

Step 53

A few tips before you start. Use more than one brush varying size, softness and opacity. Use at least 4 colors, the base color, a highlight, a midtone and other for shadow, store them in Swatches. Instead of erase try painting with the base color to correct mistakes.

Define texture directions, start with a light green R:175 G:190 B:125 and a thin brush.

Painting texture

Step 54

Change brush and use this settings R:100 G:115 B:55 as midtone color. Attenuate brush strokes maintaining details.

Step 63

Backup Starfish folder just for precaution, press Command/Ctrl + J, name your backup as Starfish Backup. Select the duplicated group, use the shortcut Command/Ctrl + E to merge it. Right click on the mask and choose Apply Mask. For the next steps a flat version of Starfish works best.

Backup

Step 64

Select Starfish Flat for a fine tuning with Adjustment layers. Don't forget to clip them all in correct sequence.

Adjustment Layers

Step 65

Create a new layer above the Adjustment layers, set a dark red color R:75 G:0 B:0 and paint soft shadows.

Shadow

Step 66

Add a new layer with Blend mode Overlay, grab a soft brush to paint specular highlights.

Highlight

Step 67

Now we can add a final detail to the image, a subtle sand relief. Use a soft brush to paint a line at the bottom of Starfish. Apply the color R:215 G:210 B:195.

Sand Relief

Step 68

You have reached the final step, add a last, however important Adjustment at the top of all layers. This will give a warm look to the image.

To add the extra bubbles you can render in Cinema 4D or copy and deform the ones present in the border.

Color Balance

Conclusion

Although the process seems complex, the techniques I have used here are simple and require more hard work than supernatural powers. The scret is to trick the eye. I hope you have learned useful things that may help you create shiny works. Thanks for completing the tutorial and keep practicing.
