Hi Neil,
Haven't tried it, but this is not what prevented my skydome from showing up.
I had placed the illumination texture under an illumination shader, while it
should have been under a surface properties shader. Don't have a clue why
but it works. Thanks though.
It works because surface properties is used even if there's no lights in the scene; surface illumination is used once per every light. This is why the HDR suddenly worked when you added a weak light to the scene.
