#92 surface:dPdtime

[Kevin Egan]

The surface:dPdtime variable does not seem to return valid values in a gather statement, whereas other variables like surface:N seem to work fine.

gather("", P, shadDir, 0, 1, "surface:dPdtime", VShad);

In the attached example this translates to a black image for cornellbox_shad.exr. Also, the example uses a raytrace hider and hider "samplemotion" set to 0. I believe this problem exists with any hider settings.

Thanks!

Kevin
