Rotate clouds and flash in VR (Flyinside XP 1.71)

[gonvise]

Hello,

I am using the last version (1.71) of Flyinside to fly xplane 11 in VR.  Due to the poor representation of the clouds in Xp11, I have opted for the software SkyMaxx Pro 4, since xenviro doesn't meet my expectations (I'd like the 3D "puffs" clouds, xenviro is good in the distance, but very poor in the representation of nearby clouds).

But in Flyinside With SkyMaxx Pro 4, some clouds, at the distance (not only nearby clouds), rotate when I move my head. Also, sometimes the clouds flash, very often. On the other hand, Xenviro looks ok.

Can you investigate this please? I understand that not everyone fly in VR, but FlyInside works very well with XP11 and the results in VR are amazing.

For now, my best advice is to lower SkyMaxx Pro's cloud draw area setting if you've turned it up. You may have it so high that what you're seeing in the distance are the 2D "imposters" we use to preserve performance. Lower draw area settings will also result in more individual cloud puffs up close, which will make the clouds more volumetric and VR-friendly.

You might also consider changing SMP's overcast setting from "HD Cloud Puffs" to "dense particles" - these too would be more VR-friendly because they use smaller particles.

Ok, thanks. I will try the suggested changes and comment.

Hello again... With less cloud draw area, less single clouds have the effect... Perhaps a pair or three. They disappear when I dont look directly forward (sorry, before I said that they rotate...).

Unfortunately we don't have FlyInside or a VR rig to test with here. It sounds like something's a bit off with the view frusta we're receiving from X-Plane in this setup.

If you have any contact with the developers of FlyInside, it might be worth asking if they are setting sim/graphics/view/world_matrix and sim/graphics/view/projection_matrix as each eye's view is drawn. That's how we get the view frusta that we draw and cull the clouds against.

Same issue here with the rotating clouds in vr with version 1.73

Can you tell me some more specifics about your hardware and software setup? I don't use VR so I really have no idea what you're seeing or what might be causing it. But I'm open to trying it and seeing what's going on.

In my case its with the oculus rift + xp11 + skymaxx pro 4.0.1.. other cloud engines dont have this issue.. i tried to record a video, but unfortunately the view that gets recorded doesnt show it.. only in the goggles.. it was always an issue with p3d.. you look at a cloud, turn your head, the cloud rotates as you rotate.

My Oculus Rift is on loan to some contractors, but if I get it back I'll take a look. I suspect the cloud rendering technique we and P3D use has some smoke and mirrors that VR exposes a bit more. There is a longer-term effort to produce a new option for cloud rendering in SMP that may be more VR-friendly, but it's too soon to really talk about it.
