Getting hdri cubemaps to work

Just trying to get a skybox working, but it’s always rotated and I haven’t been able to find a solution.

Any ideas?


It looks like a cubemap arrangement issue. I am still learning the fine details of this but I know that UE formats the wrap differently (sides are always vertical oriented in UE) to traditional game dev ways.

Here is an Unreal Doc covering what I think is happening.
