Final product image
What You'll Be Creating

Follow this tutorial step-by-step to create a 3D Smartwatch model that you can use in video games, graphic design and illustration projects whilst learning Cinema 4D quickly. 

Some of the skills you'll learn in this tutorial include creating basic 3D modelling, importing reference images, adding lighting to the scene and basic rendering techniques.

In the first part of the two-part tutorial, I showed you how to:

  • How to Import Reference Images
  • How to Prepare for Modelling
  • How to Model the Smartwatch

In this, the second part of the the tutorial series, I'll show you how to:

  • How to Create Coloured Materials
  • How to Add Lighting to the Scene
  • How to Render the Smartwatch

8. How to Create a New Material

Step 1

Located near the bottom of the screen there should be a material selection window. Click on Create > New Material to create a new material to use that you can edit. 

Materials are used to colour in the various objects and parts of the Smartwatch.

Create a new material

Step 2

Double click on the new material icon (displayed as a sphere). This brings up the Material Editor, where you adjust the various properties of the material such as the colour, transparency and reflectance. 

For this particular style you'll only be interested in flat colour (Luminance).

Choose Luminance

Step 3

Tick the button for Luminance and untick the boxes for Colour and Reflectance. This will give us the cel shaded look for our final image of the Smartwatch.

Unticl Color and Reflectance

Step 4

Colour the Smartwatch, starting with the body, by adding the material to the object. Simply drag and drop the material to the object using the mouse. Drag and drop the material onto the object listed on the right of the screen. 

This process is repeated for the other parts of the Smartwatch. The base colour of the Smartwatch is as follows:

  • R: 201
  • G: 197
  • B: 198
Adjust the color

Step 5

Apply this material colour to the Smartwatch buttons as well

Add the material to the buttons

9. How to Adjust the Material Properties

Step 1

In the Material Editor, click on the arrow button next to Texture and select Sketch and Toon > Cel from the menu.

Choose Sketch and Toon

Step 2

Click on the new Cel button that appears next to Texture to bring up a new menu.

Click on the Cel button

Step 3

In the new menu, adjust the settings as follows:

  1. Change the Diffuse to match the image at below. It should be grey scale with the colour getting light from left to right.
  2. Untick Camera.
  3. Tick Lights.
  4. Tick Shadows 
  5. Select Multiply from the drop down menu.
Select Multiply

Step 4

Select a colour by double-clicking on the colour option box . 

The Material Editor gives you many different options for choosing and picking the colour. These include RGB, HSV etc. Choose whichever option you're most familiar with as a flat colour. Because of the Multiply shading mode, the different colour shades also appears in the material.

If the material has already been applied to the model, the colour of the model is automatically adjusted to the new material colour. This is useful if you change your mind on a certain colour or a certain part of the Smartwatch model.

Use the Color Picker

Step 5

Because you've already applied the material to the model, the colour of the Smartwatch is automatically adjusted to the new material colour.

10. How to Adjust the Shading

Step 1

To get a  better idea of the shading and how our render will turn out as you work on it, click and hold on the Render Button and select Interactive Render Region from the menu. 

Choose Interactive Render Region

Step 2

Use the mouse to adjust the window so that it fits around the Smartwatch model. Look for the very small arrow on the right hand side of the window and use the mouse to drag it to the top right corner of the box (this increases the resolution). 

Decrease the resolution by moving the arrow down if you find that the performance is decreasing.

Increase the Resolution

Step 3

To change the way the light source is facing go to Options > Default Light.

Add a light object to the scene if you are more comfortable working that way. 

Change light source direction

Step 4

Change the light source in the Default Light window. Click where you'd like the light source to come from on the sphere and it'll sync with the view port. Experiment with different lighting positions to come up with a lighting situation that you like. 

This is adjusted at anytime so you can change the lighting again if you changed your mind.

Click on the Default Light

11. Other Lighting Solutions

Step 1

To set up the basic lighting, go to the Floor button located in the top menu bar. Left Click-Hold and then select Physical Sky from the menu.

Choose Physical Sky

Step 2

Ensure that Physical Sky is selected in the menu on the right, a new menu appears on the bottom right of the screen. Select the Time and Location tab and choose a time using the left and right arrow keys. 

This changes the lighting of the scene (according to the time of the day). Choose a suitable time to light up the scene. You'll see how the lighting affects the scene in the viewport.

Choose Time and Location

Step 3

To add a light to the scene, select the Add Light button in the top menu bar at the top of the screen.

This will create a Light Object which you can move around the scene. Move the light object using the Move Tool to a suitable position.

Select Light Object

Step 4

To customise the lighting further, experiment with the light object options in the bottom right of the screen. Here you can adjust the Intensity, Light Type and even Colour.

Adjust the Light Object

12. How to Colour the Smartwatch Screen

Step 1

To create a new material we can duplicate the material by holding CTRL on the keyboard and then using the mouse to click and drag the material to the side.

Duplicate the Material

Step 2

Double click on the new material to open up the Material Editor and select Luminance. From there change the colour to the following:

  • R: 56
  • G: 47
  • B: 66
Change the color of the Luminance

Step 3

Apply the new material to the screen by clicking and dragging it directly onto the object.

Color the Smartwatch screen

13. How to Colour the Smartwatch Wrist Strap

Step 1

Create a new material. Duplicate a previous material in order to keep the settings from before.

Double click on the new material to open up the Material Editor and select Luminance. From there change the colour to the following:

  • R: 70
  • G: 69
  • B: 65
Choose a new color for the wrist strap

Step 2

Apply the new material to both of the wrist straps by either clicking on the material and dragging it to the objects via the viewport or via the object list window.

Add material to the wrist strap

14. How to Render the Smartwatch

Step 1

On the top menu bar, click on the Render Settings button. This brings up the render settings window.

Click on Render Settings

Step 2

In the Render Settings menu, change the options to what you need. First you will need to tick the Save Settings to select a file location, file format and alpha channel.

Select Alpha Channel if you wish to keep the background see through. This is useful if you wish to add a background to the image in Adobe Photoshop.

Enter Save Settings

Step 3

In the Output Settings choose the resolution, height and width of the image. 

Enter Output Settings

Step 4

To ensure that the Smartwatch render is nice and sharp, go to the Anti-Aliasing settings. Select Cubic (Still Image) which can be found under Filter

Choose Cubic Still Image

Step 5

To create the final image of the Smartwatch, click on the Render button. Remember to make sure that you've selected the right view in your viewport (front, right, left or perspective etc.) and that you're happy with the camera angle. 

Choose a suitable angle in the viewport by navigating around the scene.

Click on the Render button

Step 6

For more control over how the final render looks, create a camera object to help. Find a suitable view using the viewport first and then click on the camera button. 

This creates a camera using the current view in the viewport. Check out the camera settings to see how they will affect the final render.

Click on the Camera button

The End Result

Wait for the final render to finish. Once the render is complete, repeat the steps above and change the camera or the view port to create a new image from a different angle. 

Throughout the course of the project you've learnt how to:

  • Import Reference Images
  • Prepare for Modelling
  • Model an Smartwatch
