- In the last station we applied the material to the hole object. Now we select a few faces to color only parts of the object surface.

A colored cube
To be able to color of one or more faces, select them. At first the script:
#!bpy """ Name: 'colored_cube.py' Blender: 2.7x Group: 'Material' Tooltip: 'Colored faces' """ import bpy red = bpy.data.materials.new('Red') blue = bpy.data.materials.new('Blue') yellow = bpy.data.materials.new('Yellow') def setColor(obj, material, color): material.diffuse_color = color material.specular_hardness = 200 obj.data.materials.append(material) def colored_cube(): """ A three colored cube """ bpy.ops.mesh.primitive_cube_add(location=(0, 0, 0)) ob = bpy.context.object ob.name = 'my colored cube' setColor(ob, red, (1, 0, 0)) setColor(ob, yellow, (1, 1, 0)) setColor(ob, blue, (0, 0, 1)) # apply the colors for face in ob.data.polygons: face.material_index = face.index % 3 if __name__ == '__main__': bpy.ops.object.select_by_type(type='MESH') bpy.ops.object.delete() colored_cube()
Name the colors
Every color should have a name. This is the first Step.
Add the materials
This is little bit tricky, to add a color for each face. Step by step:
All faces of an object (a cube has six) are saved in a list of polygons.
In a for loop wie iterate over this list.
The index number from the list is divided by three with the modulo operator.
So we get three possible results 0, 1 or 2.
Each number is connected with a color.
Finally the color number is assigned to the material index, because materials are also managed with an index.
|hint:||In old tutorials before 2.68 faces are selected from a list named faces. Now the new list and name is polygons.|
