Mental Ray query

[Tommy L]

When all the geometry in your scene stays the same but the camera moves, is it possible to un-tick the 're-build (do not use cache)' box in the final gather dialogue? Or does it have to re-calculate the final gather for each frame?

Thanks in advance,

Tom.

Well, have U tried it on a simple file?

 

From my experience, yes it will re-calculate on each frame, but MUCH quicker than on initial. Photon map is traced only once, though.

Hope it helps.

Cheers mate, will try on simple file.
