I'm rendering this massive scene that is so large that I have to render it in separatem passes from separate files. However, I want to do one cohesive z-depth pass so I can do dof blur and so atmospherics in post. Now I've gotten the z-depth pass to render, but i need it to have the same motion blur as the rgb elements or it's useless. That's where I run into problems. The blur keeps putting me over the memory limit as my boxes only have 2 GB of RAM. (not even sure if Maya can handle more RAM than that)
I've tried all sorts of things: 2d blur, 3d blur, saving motion vectors... all of it fails. The only thing I've gotten to work is rendering my z-depth with a shader in the rgb channel, and then doing a separate render that saves motion vectors. The problem is, I can't figure out how to get the blur2d tool to apply the motion vectors of one file onto the rgb of another file.
Does anyone know if this is possible?
Eternally thankful to whomever may prove to be my savior,
