FIX:

I've found that in order to get these textures back, I need to either move ~ 10m in any direction in-game, or access F2 view, and move ≥ 10m by using mouse and/or scroll wheel to zoom ≥ 10m away.

Note that if you leave your F2 view set to a distance ≥10m away from the cockpit, then a simple switch into F2 and back into F1 is sufficient to regain the rendered textures.

DETAILS:


With the latest update to DCS World openbeta came many great improvements.  Unfortunately it seems new or different bugs were introduced.  One I've found, which is 100% consistent, is explained in this way:

In VR (HTC Vive), when I access the F10 map, and then come back into F1 cockpit view, all the object textures, including my entire helicopter, including cockpit and excluding a few cockpit lights, is completely black, no angles or lighting or shaders or anything just matte, pitch black.


I believe this is similar to the map bug I was experiencing in previous openbeta versions, where, coming out of F10 map view, the world would become immensely brighter, with lack of proper shaders.  Similarly, moving around would fix this issue, and likely also the F2 fix but I can't confirm that at the time being.

Likely an important final note is this was experienced with mods enabled, in multiplayer servers.  I should be able to test in the near future whether this effect is also experienced on a pure client and in single player.

Same issue with a rift.
Same fix for problem.
