Caustic effect Octane plugin

[timpeters]

I've found this beautiful effect with caustics:

Tried different ways in octane c4d but it's difficult to create something like the example.
How can I create such effect with my octane plugin 2021.1-(R3) for c4d? What are the best settings?

thanks in advance,
