RT GPU crash using fast sss2 and override material

[1funk]

There are 2 different ways to crash using attached scene


MODO 11.1 453071
V-Ray 3.52.01 27662

1. Load attached scene into the "render v-ray" layout
2. Start RT GPU

RESULT: CUDA error 700. Modo requires a restart for RT GPU to work again.




These steps actually crash my video drivers:

1. Load attached scene into the "render v-ray" layout
2. Select the shader tree > test > V-Ray override material, and disable it
3. Start RT GPU
4. Enable the V-Ray override material

RESULT: Soon after my video drivers crash

Thanks for bringing our attention to this. We'll log a bug report and will update the thread when we have any news.

I tested this in modo nightly build 28908, and the initial CUDA 700 crash doesnt happen. But when I try the second set of steps (or editing the fast sss material by enabling scatter GI), I get a different crash instead.

CUDA error 719

I'm getting this on the latest build of Vray with new Nvidia drivers. Nasty hang then crash.

Hey, funk,

Thank you for the report, Cloud please add info about GPU driver release if it possible.

Cheers,

I can reproduce the crash with V-Ray Next as well.
No need for GPU driver info.
I will take a look how it can be fixed.

Thanks for confirming vladimir.nedev

This should be fixed in the nightly build from 2019.02.17 .
