Hi, may I ask how many passes had passed for this render? Are you able to share your scene with us via our private uploader?

I have send the C4d file :)

How many passes did you render? Caustics quality is mainly dependent on the number of rendered passes, so maybe you just need to render your image for some more time?

I just change surface bump to water preset

Sorry,I don't know what you mean by "bump to water preset"
and i need the volume/hight of the cylinder.

Dear corona team, i send a file yesterday. Do you have a solution?

Hi, I also second Leo's comment. The water bump does not look realistic and has been scaled down. I hope that helps
