Howdy;

More then once my final renders have blotches, spots, and white and black stains...especially on wall surfaces...i have tried and fiddled with all the options in the render settings, lowering and also increasing them one by one...but nothing improves the render quality.  I use different light sets and domes that take advantage of indirect light.  I dont know why this happens...nor how to solve it.  One thing i do know for a fact...and that is that in Daz Studio this problem is non existant...i have used Studio in the past...and i have never seen these imperfections in final renders...hmm...wonder why that is?...

Any insight would be helpful
