@jiunlin Hi, I'm just testing VBS 1.13.2 with your own passthrough sample in the vive_openxr_sample_2.1.0_UE_5.3 project.
It seems to do the reverse of what it should.
Solid objects (the "floor" actor in the sample) show the passthrough, while the surrounding sphere, where I'd expect to see the passthrough video remains blank. Am I missing something here?
VBS app is 1.0.19.2 on the device. After hitting "A" (enabling the passthrough) the object with grid texture, below, shows the passthrough. This is the opposite of what I'd expect.
