Hello elisa_christie, after investigating the issue, we have reached to the conclusion that it stems from the fact that the scale of the Geometry node housing the VDB file was changed, and I have logged this on our end under request number (HOU-4219). In the meantime, a workaround that you can use is to go into the Geometry node and use a Transform node to change the scale of the simulation. - Example

Additionally, you might find the following information useful when working with VDB files in the future. Using VDB

1. Volume Light Cache must be OFF
2. Light Scattering Type must be set to Ray-Traced
3. Optimize Big Volumetric Grids must be OFF

Hey elisa_christie ,

The GPU crash should be resolved starting with the nightly builds from Monday, Apr. 15.

Hope that helps!
