I would like to have access for the instance index for instanced static meshes in the material editor.
I think it would provide more information about the instanced static mesh data, also you can generate a random number in a shader from this information. So you don’t actually need the RandomNumber in the instaced static mesh.
My current problem with the Per instance random is that it generates a new random number everytime i remove or add a new instance.
Also an Instance World Location node would be also helpful.
