Hi，
I try to immigrate a FPS project created from FPS template, everything works good when in FPS and I launched the FPS in Windows Successfully.
However, when I immigrate the map to VR Template ad add some simple elements in the scene, such as pick up tube, it does not allowed me to build the map any more, its always crashing. And when I try to pack or launch the project its always fail.
The Log I got when I try to build the light.
=== Lightmass crashed: ===
