Summary
So, I recently added an asset pack from FAB into my project and I’ve been moving things around to fit my folder structure and organizational preferences. While do this, I’ve run into an issue where a group of materials has begun to crash my editor anytime I open them or any mesh they’re assigned to. They aren’t used in any levels at the moment. But I can’t even open them to edit them. I’ve tried everything I can think of to try to fix it. This is the exact error it’s giving me:
Assertion failed: VTStacks.Num() == MaterialCompilationOutput.UniformExpressionSet.VTStacks.Num() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\Materials\HLSLMaterialTranslator.cpp] [Line: 6898]
If I’m reading this right, the file it appears to be referencing seems to be in my D drive for some reason? Which is odd because I don’t have a D drive. I did however copy the entire project over to a flash drive at one point that shows up as D drive when I have it plugged into the computer. But, the project I’m working on isn’t the one that’s located on that flash drive. And that drive isn’t even plugged in while I’m in the project (Although I did try plugging it back in to see if that helped which it didn’t).
I don’t know if any of that has anything to do with the error, I’m just at such a loss on how to fix this error that I figured I’d add that here in case it was relevant. Any help on how I might fix this issue would be greatly appreciated. If worst comes to worst, I will probably have to just reimport the asset pack again, but I don’t want the same thing to happen again if I do.
