Changing Shaders
 

I want to make it so when I get to a certian frame in my animation, a shader on an object changes to a different shader. I tried keyframing it, but that didnt seem to work. Any suggestions? Thnx :)

Put your original shaders in a layered shader. Then keyframe the transparency of the "topmost" shader.

Thnx Kman. Ill give that a go. :)
