Unfortunately, it’s post-Upgrade 5.0.1, and the VR template is still at it. I’m experiencing failed assertions while building both materials and lighting. And it isn’t the install or my drivers. I’ve done a clean install and went so far as to DDU my GPU drivers and completely reinstall. Also, I’m able to build both materials and lighting just fine in a “blank project” with some props added. In fact, that might be my solution for now – build the game in a blank or FPS project, and add the VR controls using Blueprint.
