Vray doesn't render...

V-Ray V-Ray for 3ds Max Issues
1

Hey guys, working on a large scale project and it has been rendering just fine up until today (large scale images, 10,000 px).

When I hit render, everything happens as normal (creating geometry, building static raycast accelerator, etc) and then it simply ends the render.

Here’s the end of the vraylog…

Just tried again having restarted max, and this time it rendered a 64x64 pixel square in the top left corner, then said it had completed.

Created a new (duplicated) vray cam and it appears to have solved the problem. This isn’t the first time I’ve had vray cameras corrupt in projects; though usually the only time I notice it is when I can’t add the camera to batch render, then I know it has corrupted. I’ve never seen it do this before.

You don’t have any region render or blowup render defined accidentally, do you?

Best regards,
Vlado

My guess… region set to nothing.

Yep. Easy to do when you have a vray region set on a low-res test, then up-res and suddenly the vray region is off the frame.

Exactly… happens to me at least once a day. First time I thought I was going crazy…
