Another Skyball example
4This one I did change the Sunsky gamma, but it is pretty much the same as the other texture for the other ball. As far as textures, its is just different. I tried to make this seem more like it was later in the day.
Oh, the Uvs are not messed up in this version I tested.
Why all the trouble to make a basic cube map... Seems to be issue with game saving Cubemaps. There are Youtube videos out there showing various ways to get them saving. But to be honest, I am not a fan of all the leg work to get the hdri to be a compatible cube map format for beamng. For whatever reason the way they rotate their cubemaps in BeamNG is not the norm. I always get confused trying to figure that stuff out. But this is much simpler. I just baked the environmental map of a mesh sphere in Blender while using an HDRI background. HDRI Haven has some that goes well beyond 8k. But I am only baking 4k. Also should note the hdri settings for brightness is not the default 1.0. I had to drop down to 0.1 to not clip the whites.
I think this solution has some promise. Until the sky gets an overhaul, that would be great. But I realize this is no flight sim game, the sky does not need to be focused on nearly as much as say... Ground deformation :P Hope 2024 brings that.
