Hi,
I want to play around with the VRaySDK a little bit. I want to cast a ray from the shaded surface in the direction of the normal and then I want to get the distance to the first intersection. The basic approach of occlusion shaders i think. Without having started yet I already have some questions. If I use the traceDir() or traceRay() functions I get a color value back, don't I? How do I get the distance to the first intersection?
the wpointCoeff from RayResult seems to give the distance from the shaded point to the camera.
Thanks in advance
Dieter
