Caustics on walls and floors issue

[csuarez]

Hello! I am attempting to render caustics up against the floor and wall but am having an issue as it looks pixelated? I'm using a smoke map for the water's bump and am unsure if the smoke map is the issue?

What CPU are you using and how long did you render? It seems that caustics did not have enough time to refine yet.
Also, it looks like you used a region to preview your caustics, and currently using regions with caustics will always result in persistent splotches. We are aware that this is a serious issue and would love to fix it ASAP.
