PUMPKIN MATERIAL

Creating a pumpkin with Cinema 4D: PART 2 By Ko Maruyama
If you need to create a 3D pumpkin for seasonal graphics (whether for Halloween or Thanksgiving), you may wish to use a 3D application to give you more control over your digital pumpkin.  In this series, I'll have some simple steps showing how to texture a previously modeled pumpkin shape.  If you haven't seen the previous tutorial, or need to create the geometry, you should check it out in the DMN Tutorial Archive.


As I noted in the previous tutorial: usually, these tutorials explore the process and tools, but this series will focus solely on the specific steps.  (Stay tuned for a QuickTime instruction with more detail about the tools).

If you need the previous model for the pumpkin, click here: pumpkin_part1.c4d

To complete this tutorial, you should have a fairly good grasp of the material attributes in Cinema 4D.  Because I cannot create a QuickTime for this project currently, I will limit the steps.  Please check the archives for the basics of handling materials.  Basically, the principles of materials haven't changed since my v.7 tutorial on the same.

You don't need to have your model loaded into your scene to create the material, but it helps.  We'll be using displacement mapping, which will effect the model based on the polygonal structure of the geometry. (See previous tutorial).

1.  Create New Material

In R9, you can now use LAYERS rather than FUSION in order to create a material that has multiple procedurals.  There are countless ways to set these up, this is just a start.



Select the "Color" parameter.  Close the color subchannels.  We don't need to use a flat color here because the texture we create will completely override this solid.





COLOR PARAMETER

2. Choose Layer from the Texture Pulldown menu.

Layers will create a container into which you can place many different combinations of shaders, including bitmaps, animations, effects and other layers.

 


To edit the layer, either click on the name bar "Layer" or click on the preview chip (which may appear black).

The next attribute window appears blank.  This allows you to add, order, examine and edit the different elements of each layer.

1. The first parameter allows you to add a bitmap image (Image).
2. The Shader allows you to add any of the available shaders in your C4D package.
3. Effect parameter allows you to adjust the appearance of the layers below the applied effect layer with varying parameters
4. Folders allow for organization (and work similar Photoshop Layer Sets)
5. Remove is a button for artist who don't want to reach for the "Delete" key which does the same (deletes the selected element)




3. Add Shader: Color (Orange)

Click on the small preview chip next to the name of the layer to edit that layer's parameters. Color allows for a solid color (similar to the basic material controls).
(To change the name of the material layer, double click the layer name)

 


4. Add Shader: Color (Yellow)

This will be the color of some yellow speckles at the top of the pumpkin.




5. Add Shader: Noise

Again, click the small preview chip next to the name of the layer to edit this if you want.

 


6. PRECOMPOSE shader.

Yes, like in Adobe's After Effects, we can precompose this layer.  With the Noise selected, right-click (or CMD-CLICK) the name of the layer.  This will bring up a shader option for the selected layer.
