Hey guys, this is a really basic question.

I'm trying to do some interior renders. Basically the camera is in a box (granted its a nicely modeled gallery), and I'm using the light template with ambient occlusion, but the occlusion only renders on the exterior of the box, instead of illuminating the interior. I reversed the surface normals to see if this would fix the problem, but no dice.

I'm sure this is a very simple fix.

also, can anyone point me to some lighting and rendering resources that go a bit beyond the tutorials that sidefx has in their learning section?


Thx alot !

i think its becouse ambient oclusion works like a sky dome.
and in your scene, the outside of the box its casting shadows to it self inside part.
try to delete the uper part of the box…

actually it is not working that way
it is sending rays in direction of the shading point normal with variation of “sampling angle”, and because it hits the surface with all rays (because you are inside the box) it returns black.

what you can try is reducing Maximum Intersect Distance parameter to value less than box dimensions
