For a small animation i am making a light bulb that symbolizes an idea. I created a simple light bulb model but the diffuse color will not animate correctly. I go into the material room and make the diffuse animated. at frame one i set it to white and at frame 30 i set it to yellow. this works in the preview but not in firefly rendering. any advice?

HAHAHAH i sure didnt forget to keyframe it surely not...
