Hot Spots/Splotches

[Trumble]

I've done a pretty decent search for the noted topic and tried a lot of the settings/suggestions given, but I can't seem to get rid of these completely random splotches in my scenes. I've attached some image examples.

They're completely random and there doesn't seem to be any rhyme or reason why they appear. I've tried jacking up AA settings, changing reflect/refract values on the materials, making the sun invisible, nothing seems to help.

Any help is appreciated.

Would need more info. But my fisrt guess would be either geometry problems, GI settings or some caustics issue.

I'm sure it's something to do with the shiny/reflective/refractive materials I've got plus a very bright vraylight material on the front of the probe. And in all the scenes the camera is "looking through" water...As in, the pipe has been cut in half, but the "water" is still in the pipe...I'm guessing that reflective materials + refractive materials + bright light ='s screwy splotches

Here's my calc/render settings...They've never failed me before...but I've never had a project that was this close up with reflect/refractive materials either...I've got a stripped down version of the scene that I can email if anyone is interested just shoot me a line (scott@trumblestudios.com)...

Figured it out....My water material was apparently unhappy with the way I was going about getting it to be see through...I had a fall off mapped to the opacity channel and no refractions...Changed it up and instantly solved...That was a good waste of 2 days hahaha...I can't believe I didn't think to check that sooner...
