View Full Version : mental ray ambient occlusion pass

10 October 2005, 10:45 PM
Hi guys,

I have not scripted a lot of rendering stuff, I am trying to set up mental ray in Max 7.0, I can script all the settings I want for the FG and GI etc, but I really want to render out an ambient occlusion pass. The easiest way I can find is to use the material override option in Mental Ray, and fire out a pass with everything covered with an ambient occlusion shader.

Is this override option scriptable, the mental ray section of the max 7 help really confuses me. Ideally I am looking for a main pass, then a shadow pass and an ambient occlusion pass, can this be done by scripting the render elements section. I guess it could be done by autmatically creating folders then getting the to render 3 times, each time for a new pass, into a new folder.

Is there an easy way to tackle this..... would really appreciate any help, I am properly stuck

Thanks all,

Could this be easier using render presets, and loading them in one after the other to render the different passes?? Would that be the easiest way?

There doesn't seem to be a way to connect via script to the Material Override, but as EverZan pointed out, a render preset would be fairly easy and it's script accessable. look up "Interface: renderpresets" in the script help docs.
