.\GenerateProjectFiles.bat -Game HandsTrainSample -Engine <full path to Unreal-HandsTrainSample directory>\HandsTrainSample.uproject

3. Open the HandsTrainSample.sln file that has been generated in the Unreal-HandsTrainSample directory.

Known Issues

• If running on a Quest2 device, you may experience low FPS when using GPU occlusion. You can either switch to the Meta Fork of Unreal Engine and use CPU Occlusions (UE5.5.4 or later) or add r.AllowOcclusionQueries 0 over a blueprint node. See LevelBlueprint as example.
