edit - I did resolve this by migrating the maps to a new project
looks like it’s trying to load stuff onto/from my D and F drives?
Using lenovo explorer WMR
On one of my projects UE4 will launch a level in VR, doesnt seem to crash
my current project seems hit or miss on a given level
VR template seems to work for just play in level, not VR mode, but with artifacts such as a black triangle across the right side of the screen. VR template editor log posted below my main project’s error
anyone seen before or know how to correct? ty
Fatal error!
