Hi,

I have a question just for clarification.

I thought that CalcTransparency´s VolumeData will give me

vd->ray->p = location of light-ray hitting point to be shadowed
vd->ray->v = direction to the currently evaluated raylight

I can confirm the first assumption while debugging, but th direction assumption seems to be wrong...so, where does this direction vd->ray->v point to???

Thanks
Samir

Both assumptions are correct.
