Corona-like caustics

Hello,
I do many Archviz renders of pools and Corona Renderer has much more superior and realistic caustics for this use case. Is there a plan to have such easy-to-use and beautiful looking caustics featured in Arnold?

(I have tried all possible arnold workarounds and none have delivered good results)

yes I have, It has not worked in a pool-filled-with-water scenario, best solution right now is to render Caustics pass in Corona and use it in the post

Both rendered in Arnold one has caustics pass rendered in Corona laid over, it adds unprecedented emotion to it.

I guess you need to use "fake" caustics. I honestly don't use caustics at all, because usually clients always want something more tone down. I believe is too "expensive" to calculate this type of effects. Corona has caustics true, but then it takes 17 hours to render a 5k image.

I don't have impression it is that expensive in Corona, I have rendered caustics down below in about 30 minutes albeit not in 5K but 1440 p. You can also render part of image with caustics. I am also sure Corona caustics is some biased trickery.

I agree that there are shortcuts to get those caustics.

Not to dis on arnold, it does produce some nice subtle soft caustics. But it just don't do the job for rippling pools.
