I have a wind shader that is working just fine when I export my meshes from Blender with the default all-white vertex colors. I multiply the WorldPositionOffset by the vertex color so that white vertices have 100% movement and black vertices don’t move at all. That works fine. But the gray vertices all seem to have 100% movement instead of the expect gradient.
Have any of you ever noticed a similar problem? Does Blender only export vertex colors as 0 or 1? Does UDK only import vertex colors as 0 or 1? How do you import your vertex colors?
