Heterogenous Volumes replaced with grey squares in viewport

For some reason, all of a sudden, all my heterogenous volume vdbs were replaced with grey squares. It almost looks like my grahics card is failing. Anyone see this before?

Hi @Midasssilver
Let’s see…
Update/Reinstall Graphics Drivers: Get your GPU drivers updated or reinstall them to address potential driver issues
Check VDB Texture Settings: Ensure your VDB assets are well configured, in particular the Volume Texture settings.
Check Unreal Engine Settings: Ensure Volume Rendering is enabled and your Viewport is configured to render volumes
Check for Engine Bugs: If you’ve recently updated Unreal Engine, try reverting to a previous version in case a bug was introduced
Hardware Check: Monitor your VRAM usage and consider testing on a different machine to rule out hardware issues
Re-import VDBs: There might have been an import issue, so try re-importing the VDB files.
Console Logs: Check the Output Log for any errors related to texture or volume rendering.
Material Issues: When working with a custom material, test using the default one in order to rule out material issues

Thanks for the reply. Im going to go through those steps and see if it makes a difference. It was weird, because it was just one of my volumes where the shader broke, then when I reopened unreal, they were all broken. I have opened another project, and I see my volumes working in there, so I know it’s not a hardware problem. Something appears to be broken in my project itself

Fixed the problem. The material had somehow broken. I had to make a new material, and link all my material instances to that one
