#96 dPdtime output seems corrupt for this scene
For my simple cornell box scene dPdtime can be output just fine. When I tried to translate this to a more complicated scene I'm finding that all pixels are set to a strange value regardless of speed (see car_motion.exr). I have a similar problem trying to output the speed of occluding objects (see car_shad.exr).
Turn off the raytrace hider or else the car triangles will be messed up (see recent bug report).
Thanks!

This is a scene file error. I exported this scene from blender/mosaic and didn't realize that some surfaces were using the plastic shader which doesn't have the custom output channel that I had in my own shader.
Sorry for the bad bug. Having output variables set to default values could help cut down on wacky behavior of this kind.
