Revit

[Macker]

Hey guys,

I've got a 3DS max model (nothing too special) of a building from Revit which a couple of weeks ago was rendering fine - even with a couple of updates to it. Today I had to update the model again, but this time round max is crashing every time I try to render the image. It gets to a certain point then I get a load of warnings, and an error:

I appreciate Revit is a terrible piece of software that hardly works with max, but what does all this mean? Ignore the fact that the materials aren't VRay materials - this was a test version with literally nothing on - a fresh import if you will, but I have the exact same errors with a fully VRay material scene.

Strangely the building will render fine when it is isolated, as will the trees, site, grass etc... But not when they are all being rendered at the same time.

Would be best to get us a scene for debugging to support@chaosgroup.com

Best regards,

Updated to 2016 and everything rendered fine. No idea what that was all about.

Thank you for the update.
