VRayVolume::shadeVolume (VR::VRayContext &rc)

[Karba]

I work on volume shader.

I have a question.
In case of ray is inside several objects.
What object can I get by rc.rayresult.primitive?

[vlado]

You get the object at the end point of the shaded volume line segment that is further from the ray origin. This may be any object, not necessarily one with the same material.

Best regards,

The problem is volume shader uses data of primitive. So it is important what primitive is traced.

So if several primitves have shared volume does vray call shadeVolume several times for each primitive?

At this moment volume shader some times can't get correct primitive to get inside geometry

Any progress on this?
