feel free to mark this thread as "solved"

how? :)

Edit: Solved done :)

Hi Manuel,

in the while I already made exactly what you said using the Hash2DGrid instead the KDTree.
I just hoped to a something internal in Cinema already prepared without caching uvw structures in initrender.

Thanks anyway
Renato.

Edit: Thanks for the links you provided.. but i already learned from that. Very useful of course.

Hi All,

I have a particular need. I'm inside the Output() of my custom shader.
I need to retrieve, from a particular UV (cd->p), the corresponding surface point of current RayObject. Maybe there is something that i don't know to do that while rendering is in progress.

Thanks in advance :)
Renato T.

EDIT: I'm sorry, i meant from a particular UV not the current cd->p. So, inside the Output() would be great to ask for any UV value and get the surface coordinate.
