I'm having a problem using HairVideoPost::TraceRay.
p and v appear valid, but hit and d are not being assigned anything and TraceRay returns -1 (NOTOK?).
I am testing it in a scene with the Hair post effect set to Raytrace.
Here's some sample code in VideoPostData::Execute
What am I doing wrong here?
