The PMC will start shining, when you start having overlaying caustics object and when you have different IOR values, e.g. a Liquid inside the Glass or a bottle. Also check out "nested caustics" as it allows you to tell octane which mesh is nested inside which for them to be properly calculated. And Fake shadows is also somewhat relevant for caustic shadows I think and for them to be properly rendered I think you need alpha shadows activated in the render settings. If you think the caustic shadows are too smooth, play with Caustic Blur. I also recommend reading the Cinema4D manual along with the Blender one as it offers many more pictures and shows you what which settings do visually. Update: Fake shadows are only there for glas objects, not to calculate caustic shadows. So don't check fake shadows if you want realistic results.

Great! thank you!
Thank you a lot!
Wow so easy to make caustic in octane, for the lighting do you use hdri only?
Actually I just used a plane light on the left, no hdri
thanks for sharing this man!!!
Thanks for watching!
Hi, Caustics in Octane are not good looking at all…
LuxCore has some pretty good caustics, but I think Octane does a good job.
I recently tried comparing a caustics set up in corona to octane. Caustics from corona blew octane away, in less time as well.
I wonder how caustics will look in new version of Blender in Cycles(it's now in beta).
