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

Not sure why this is happening. Is this a known bug ?

Anyone got any ideas? Really need to get this sorted. Thanks

Which version of V-Ray are you using ?
Please make sure to use the latest stable release (for Max it is 3.40.03). 3.40.02 and 3.40.01 might have this problem on some machines.
If the problem persists, try turning off hardware acceleration and give more information about the machine hardware and drivers versions.

Thanks,
Best,
Blago.

I updated all the machines this morning and it seems to have resolved the issue. Cheers
