[4.9 P4] Several problems with VR (and texture streaming)

Hi ,

I made some additional observations:

  • This seems not really be reproducable under normal conditions. I had to re-open the project three times now in a row (the first two times, the textures loaded as spected). And then, the textures were loaded suddently when I started a PIE session (and stayed there).

  • If a HMD is even attached when the engine starts, the texture streaming never works (regardless of the PIE mode)

Here’s a screenshot from 4.8.3 with ‘stat streaming’


The same with 4.9 P4 (and ‘stat streaming details’):


Maybe this is another side issue of [4.9 P1] "isHeadmountedDisplayEnabled" always reporting TRUE - XR Development - Epic Developer Community Forums (reported for Preview 1 already but still unfixed). Maybe the player’s position is reported wrongly if there is a HMD available and erroneously reported as enabled and active no matter what.

BTW: There are some additonal strange error regarding ‘/Script/OculusRift’ on project load time:


For some reason, there are also some errors reported for my function libs (but they work and I can recompile them like normal)

I can only repeat myself:

Please don’t release 4.9 in this state or at least patch this in the upcoming weeks.

Do not the same as with 4.8 (where VR was broken also). Oculus doesn’t support SDK 0.5 anymore with the current Runtime 0.7 so you HAVE to use 4.8 or 4.9 now as a developer.
