Title: Caustics and dispersion
Post by: Paul Jones on 2017-11-25, 15:50:37

I've got to produce some sample render of some jewelery, and will need dispersion and caustics. Having done some years ago in finalrender what was great was to have a separate Caustics RE, and also a caustics multiplier per material. VMC and bidir seems to have disappeared at the moment, any info would be appreciated!

Unfortunately Corona does not handle caustics very well right now, but improvements are planned: https://trello.com/b/EfPE4kPx/corona-road-map-3ds-max

For now, you can either:
1) Lower MSI to 0 (or set it to some very high value like 200+) and use dispersion + caustics enabled
or
2) Try with bidir/vcm/others. They are still there (in devel/debug), but they may not support dispersion. Here is how to find them: https://coronarenderer.freshdesk.com/support/solutions/articles/12000021288

I did a short tutorial for rendering caustics with ease in corona:
