Hi all,
I have a scene all ready to be rendered, and I have been struggling to get it to look right with MR when I batch render.
When I render any given frame with the render preview window, it looks perfect. When I render any given frame with the batch renderer, and only specify a single frame, it looks perfect...
However, when I render a sequence using the batch renderer, it seems to ignore the refrigerator light and make the shadows blotchy (see below, and please excuse the poor image quality, had to make the file size rather small).
I am using Mental Ray for Maya 5.0, and I have Final Gather turned on. At first I had turned off "Final Gather Rebuild" to save time, and I thought this was the problem. So, I turned it back on in order to calculate the gather points for each frame. The rendering took much longer, and looks a little better, but it still seems to ignore that second light source...Perhaps I need to turn on "Shadow Map Rebuild"?? I don't see how this would magically make the second light illuminate rays though...
The only other thing I can think of, is that I had the second light keyed, so that it was off from frame 0-70. I'm rendering this in layers, and as you can see the door of the refrigerator is not there. It is being rendered in a different layer and from frame 0-70 it is closed, and thus blocking the light and objects inside the fridge. I figured that by turning this light off, even if it wasn't visible, would decrease render time. I don't know if it did or didn't, but that's what I did.
Anyway, do you think MR is having a heart attack when I try to batch render with the light off from 0-70 and on from 71-292?? Perhaps lights need to be on at all times during the render sequence in order for MR to calculate them??
If anyone else has had a similar problem, or can give me some insight or a potential fix to the problem, I would really appreciate it.
thanks!
