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:

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
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:
