as written in the title, i have a problem changing the material of a vertexGroup using Python.
So i have an object with different vertexGroups. And now i would like to change the color of a specific vertexGroup. How can i do this???
I really read the docu, but i can’t find anything. How can i access vertexGroups? Changing the color, i thought the easiest way to do this, is to define a different material and switch to this. Am i right? But how?
no i dont think a material is related to the color of the vertex. So changing the material wont help you. It must be a seperate parameter. Vertex group are in bpy.context.scene.object[name of the object].vertex_groups[number of vertex group or name]
The thread title and the post specify NOTHING since there is a clear confusion between material and vertex color. Two diffirent thing that are completely unrelated.
there is no materials for vertex_groups.
Also even though the title says about materials, he then ask for vertex colors. By the way , vertex color is unrelated to diffuse and specular color and in no way related to the material data structure beyond use_color_paint and use_vertex_color_light , which are Boolean types and in no way affecting or editing vertex_color.
Assigning a material to an object’s vertices , is a simple procedure, you select the object, go to edit mode, selected the vertices and call bpy.ops.material.new() and then bpy.ops.object.material_slot.assign() to create and assign the material slot and the corresponding material to the selected object’s vertices. BUT !!! THIS IS NOT vertex color editing or creation for a vertex_group color .
thanks for your help. I’m quite new to Blender so it’s possible that i don’t distinguish everything correctly. In the attachment there’s a blend-file where i have a sphere with 1 vertex-group. this group has a different material than the rest of the sphere. Thus a different color.
That’s what i want to do, but using python.
I check out your ideas and write later again! Thanks so far.
