|Summary||0006126: Moving Sun via Spring.SetSunDirection() casts a black "hole" in the skybox|
|Description||Moving the sun via Spring.SetSunDirection() on every update (following a day/night cycle) causes a black "hole" in the sky box as shown in those images.|
On the other hand, the "sunflare" doesn't move at all, while that black hole does and seems to follow the path the sunflare should be taking.
The shadows from units/terrain properly update with the sundir, so it seems it is only affecting the advsky (sunflare/skybox).
|Steps To Reproduce||You can reproduce by using this:|
sunframe = math.random(0,8500)
sunframe = sunframe + dt/4
if sunframe then
Spring.SetSunDirection(math.cos(sunframe/15), 1+math.sin(sunframe/16), math.sin(sunframe/15))

Looking at https://github.com/spring/spring/blob/bdb71cde67c8d5caf32fdc115f41b017fb1ddace/rts/Rendering/Env/AdvSky.cpp#L49
I see the sundir (and therefor sunflare) only update once on advsky init?
My 1st guess was that the sky is drawn and takes account of the new sundir: leaves a "gap" in which the sun should be drawn and that would be the "hole", while the sunflare itself isn't updated, which leaves an unmoved sunflare.
|I forgot to mention, this is on 104.0.1 - 968, but happened at least since 103.0.|
