[REQ] Caustics pass

Post by mark21X » Wed Jul 19, 2017 3:18 am

I sometimes use the rendered image to a composition, so it is very nice if we had not only the shadow pass but also the caustics pass. It is best if we had other render passes like reflection, direct/indirect lighting and so on.

shadow pass doesn't include caustics
There are the ways to "virtually" get caustics pass, such as render the scene with black ground plane and mark transparent object as invisible, but we can't get true caustics pass from those method. Plus, if the scene was very complex we cannot do such operation to each objects in the scene by hand.
"virtual" caustics pass
Indigo can produce very nice caustics, so it is very nice if the team had implemented this feature :D
