Caustics artifacts

Hey guys,

Hope you are well?

Been a while since I been in the game and been experimenting with caustics, I have used the quick workaround using a standard spot in Max.

However, I have noticed the higher I raise the caustic subdivs on the light, the more pronounced these little speckles become.

3500 subdivs

1000 sub divs

How can I eliminate these speckles?

Am I missing something?

My caustics settings are checked and have the standard settings unchanged.

Many thanks


crisis adverted I had a second hidden hdr in there without caustics turned off, so this was conflicting
