Hey Mark!
The error is a bit generic. Pasting it here:
// Error: file: C:/Program Files/Autodesk/Maya2023/scripts/others/pluginWin.mel line 934: Unable to dynamically load : D:/snip/Quixel/MSLiveLink/DHI/plugins/Windows/2023/MayaUE4RBFPlugin2023.mll // The specified module could not be found.We also thought that might be the case, so we attempted to run an shutil copy operation to put the .mll files in a generic appdata location. This resulted in the same error. If I copy the .mll one directory higher, it works, but only if I do this without python (I have to manually use explorer to move the file). The same was true both in appdata and in the p4 directory location. Sorry that’s such a strange, narrow case! For what it’s worth, the EmbeddedRL4.mll does not have this issue. Only the two Maya RBF .mll files.
