Weird buggy render

[zhenka22]

Hi all

I know that Maya's DOF is crap, but to humour myself i thought i'd give it a go on one shot. For some reason, in a few sections of the shots, a line appears behind which everything is more blurred, and then it dissappears. Looks like it's some form of clipping plane with the camera, maybe the focusing distance but for a few spots it comes up really sharp.

Here are a few thumbs...see what you think.

Come to think of it, in a completely different scene i have had issues with inconsistent lighting, where when the camera moves vertically the brightness of the scene begins to flicker.

Anyone had this before?

It's pretty hard to make it out in the stills but it is quiet prominent in the movie.

The only other thing worth mentioning is that this was rendered with maya software, and the main light source had a light fog with a 3d fractal mapped to it.

Also with the other flickering issue, that occured when rendered with maya software, and mental ray on 2 seperate occassions.

Have fun with this guys! ;)
