Mentalray prob. in 3.9

[juan-sanchez]

I've got a problem rendering using mentalray in 3.9,...
It's one particular scene using a textured wave animation, a transparency mapped backdrop and lots of animated lights that's causing the problems.

On some machines it's sweet,...but on others any attempt to begin rendering results in a full-on crash,....without the 'niceities' of a 'will attempt to save' warning.

The scene has 'some' type of parallel to star-scape imagery, though it's not a 'space' scene, but I'm wondering if there's no obvious advice to be offered regarding mentalray,..if there's maybe some kind of web-resource for info on 'space' scenes that might help me...

Any ideas would be very much appreciated

Are the "crashing" machines dual processor? If so, run mr twice with the -threads option set to 1. This way it will not split it's calcualtions across 2 cpus, instead it will run 2 totally seperate mr processes on each. This was what I used to do when rendering with the old lume shaders. (they had a bug that prevented them from multi processor rendering)

Cheers for the reply Ed, it's not on DP's though, it's on single Athlon 900's with GF2 Vid cards it crashes, the SG's handle it fine, as do the DP P4's with GF3 vid cards.

The PC's, I believe, run copies of 'exactly' the same application, as they're all on the Uni's network, I guess the App's held on a central server.
I can get the technicians to play about with the installation etc, if that'/s be the problem,...but it seems more like the machine itself - maybe the GF2 GTS cards or drivers ?
