I’ve been trying to use ambient occlusion in post via VRayExtraTex_Map with a VRayDirt txture in render elements however my background environment is always back in the render pass.. is there a way I can get it to white?
It’s noticeably faster than using GI ambient occlusion.
its black because its empty (alpha) most likely. If you are using it in comp to multiply then you first need to merge your occlusion with a white bg then multiply. You can’t get it solid white because of the alpha so, only other workaround is to re-render as a separate render job with env set to white.
Another approach:
You can add a fully transparent dummy sphere to the scene and additionally set Matte On, Receive/Cast shadows off/ Visible to GI Off; to be sure that it will not affect the beauty pass.
