Unhandled win32 exception errors in vray.exe

V-Ray V-Ray GPU Issues
1

RT was working great, but all of a sudden in one scene i get unhandled exception errors when activating Activeshade, during the Waiting for image data… stage.

I’m getting 8 of these errors, probably because i’m using 8 cores.
I suspect it’s due to materials, since i was working on that mostly.

Errorcodes are not the same each time, i’ve seen 1312, 5040, 4468, 1288..

WinXP x64, Max 2009 x64, Vray 1.5 SP3 x64

Edit: When using a global material override RT works fine, so it’s material related. I also noticed that with procedural Tile-maps the color and fade variance aren’t visible in RT.

Found the culprit:

- When using a Tile map and using Pattern Type: Custom, if you modify Row and Column editing RT will crash.

Even when switching back to for example ‘Stacking’ and the Row and Column editing is grayed out, if there are other numbers there than: Per Row = 2, or Change = 1, RT will crash.

Yep, this is fixed already. If you would like a fix, please email me to vlado@chaosgroup.com
