mr..black spots

[paragmokashi]

i am in a big mess...
as i dont know much about mental ray i ve followed some tutorials... but when i want big size out put iam getting black spots on the rendered image...

i am uploading a crop render of that area.. u can see black patches on it... but when i rendered the same image with very low fg i. e. 10 it didnt show any spot..
later i rendered it with 250 fg. it showed black spots

Hi,

I recommend you to try the dl3d_BlackSpotsRemover lens shader, available at http://dl3d.free.fr/. It works in this situation, which seems to be yours : the number of black spots increases if you increase FG photons number.
I think it's because MR returns a floating point value or undefined value for a pixel...

I think i read some posts from the author there, dlanier I suppose. If it's true, thanks a lot to you David, it saved me during an anime rendering. Merci beaucoup ! ;)
