It works beautifully in 4.18, but I'm trying to import my work into PavlovVR (which appears to be built in the 4.15 version of the engine, or the template for it is). I would be happy to import the assets into 4.18 and migrate them to a project from older version but that doesn't seem to work either.
If it helps, the project log hits me with with "Failed to load ANSI text file: [users/x/x/x/x/x/x/x] materiallist." before crashing. I also tried rebuilding the masterlist but that didnt help either.
If there is another way to work around this, I'm open to suggestions.
Also, you can d/l the .bsp from here:
