Does High Fidelity support HDRI skybox textures? In EXR or HDR formats?
Because if it doesn’t, it should.
These are critical for realistic lighting. At least one of High Fidelity’s competitors that I know of already supports them.
Aside from being more realistic, every time I’ve used PNG for my skyboxes in HF there was very ugly, hideous banding of any gradients in the texture. I don’t know what Interface is doing to them but it does this with any PNG skybox I use.
