[Bf-committers] Material system - function to get the value of a material?

[Ton Roosendaal]

Hi,

After discussion topic on IRC, this conclusion came out of it:

It is safer and more future proof if Modifiers don't link to a  
Material. Materials are a candidate to further evolve a lot (node  
shading, support for other renders). Have this integrated directly in  
modifiers is making things to complex, especially because no shading is  
needed for modifiers, only texture. And not to mention the Material  
then still can be used for rendering, giving potential conflicts when  
same Material is used in a Modifier.

Better is to only use a Texture in a Modifier, and use similar code as  
used for the Texture node in Compositor now. Mappings for this can be  
provided locally in the modifier then.
