Baked Baldness map query.
Hope you can help.
I've made, attached and baked a baldness map for some fur to a nurb surface. My problem is that it renders fine in any single frame on the time scale but when I try to batch render the scene with the length of the fur keyframed to grow I get no baldness map. I can press the bake key in the attribute editor for the fur before the first frame is rendered and it will show but why should I need to do that?
Any ideas to help me would be gratefully recieved.
