GPU Fatal error when using bevel shader in Raytracing mode

PastyPict · May 11 2025

I've been using the bevel shader in raytracing mode as demonstrated in the Marmoset Toolbag tutorial video showcasing what's new in Marmoset Toolbag 5.

The process has worked wonderfully for a while to speed up making trim sheets for game assets, but for the past few days now it crashes showing the message the marmoset is now closing due to a Fatal GPU error.
I've attempted to trouble shoot and look for potential solutions online.

I have updated my GPU driver, reinstalled Marmoset Toolbag 5, made sure windows is up to date and increased GPU Time (secs) to 30. No difference.

Any advice on how to fix this issue would be greatly appreciated as I have found baking this bevel shader into the normal map to be highly efficient and a valuable asset for me.

My specs in case that is needed for determining the problem (none of my specs are overclocked, and they have remained unchanged since before I got this error):

OS - Windows 10
DX Version - DX12
GPU - AMD Radeon RX 6950 XT
CPU - AMD Ryzen 7 9800X3D
RAM - 64GB 4800MHz

I have also tested this on simple meshes including a simple cube mesh. So it doesn't appear to be due to dense geo.

whoa this has been a while, sry you ran into this but ROLLING BACK drivers for a lot of people seem to have helped recently.

its all over the tech videos that a lot are running into issues and leaving the raw driver upon installing for the first time no updates to driver also seems to work. People said going back 1-3 years or so on drivers is the move to make when running into these issues till they fixed whatever they are doing with their installation drivers.

hope that helps, you and or others.
