After sorting my “Tree” Folder with Mashes, Texures to a new place and restart my Engine i get this failure on startup:
“Assertion failed: VTStacks.Num() == MaterialCompilationOutput.UniformExpressionSet.VTStacks.Num”
Can´t Start my Engine and my Projekt anymore.
Ideas to Fix it?
Did you ever find a solution to your issue? I am also running into the same problem after reorganizing my project folder. I updated all of my retargets before removing the old file locations. I seem to have multiple materials causing failures, with no clear path to fix them, as I cannot open them for editing without crashing the editor.
