Yeah do what Tim said - that used to fix that for me. Empty scene - hit 7 - open your scene

What i did is, every time i opened up that scene i would call the explorer, go into the application mode, browse all the way up to the material library. If it loaded them into the scene that way i could then invoke the render tree without a crash...

The only work around solution was to open the rendertree first (in a clean scene) and than load the scene. I thought it maybe was caused by issues with the workgroups as it seems the crash was related to the rendertree loading some shader/rt_compounds when opened first. But I didn't had the time to investigate the problem in detail. So the workflow was open SI, hit 7 and than load the scene. Cheers Tim I'm still having crashes on one particular machine using SI 2013. on one particular scene, a big 500Mo object from cad, as soon as I hit 7, XSI crashes. I have a Quadro 4000 I already updated the drivers last month. Now I wonder if there are some settings I should tweak. This doesn't happen on other machines. It opens fine on a quadro 1800 machine. Anything to check ? any settings files to delete ? Would greatly apreciate advices.
