Hi, so I'm having an issue that I think I resolve every job, but it keeps coming back, and my prior solutions end up not working. I'm hoping that this image I upload will describe it best:
[ATTACH=CONFIG]45265[/ATTACH]
I am using 3ds Max 9
I am using Mental Ray for rendering
I am using Final Gather (settings should show up in the image)
I am rendering out a 320x240 pixel image, and enabling the read/write Final Gather Map.
After that rendering, I click on "Read Only (FG Freeze)" and render out a 3200x2400 pixel image (these images are usually blown up very large for marketing displays).
I do that because I read on this forum a number of times that rendering out a small image with the read/write final gather map, and then freezing it and rendering out a larger image will be fine.
What I'm finding is that when I render out the smaller image first, I get these weird dark splotches on the corners of my walls. But when I render out a much larger image first, the splotches are not present.
Does anyone know what the deal is?
