Help please:Blotchy booleans?

[chunter3]

Hi everyone,

 

For my project, I booleaned out my stucco lines from the wals I created and now when I do a test render i can see little blotches on the face of the polygon around the cuts...I have not added a materials so maybe this will go away when I do that? I hope I dont have to create new geometry because of this....Any thoughts? I am using vray as my renderer if that has anything to do with it...I know that i get blotches in the render if i have an array of an object overlapping itself so Ive deleted excess objects in those instances, but im still getting it on the booleaned geometry....I attached a sample here...Thanks for any input![ATTACH=CONFIG]41204[/ATTACH]

Your general GI settings could be improved here..overall

For the overlapping geometry, In the Secondary rays bias, put 0.001 instead of the default 0.0.( This can be found in: Render setup (F10) V-Ray tab, V-ray global switches rollout, lower right section.)

it looks liek poor GI to me - rather than geometry

i would never use booleans in max as they create awful uneditable messy geometry.

for me it look like there are floors right behind stucco.. that may cause splotches if GI density is too low. Also check for interpolation samples cause dark samples from non lit area can be interpolated in that points with darker result in final GI coputation
