Solaris has a "dome" light.
A dome is a hemisphere.
In openGL the dome light looks like a hemisphere.
However light from a solaris dome light appears to be spherical, like an environment light. And there is no "clip to y positive hemisphere" switch.
Is this light still in development?
Thanks

'dome' is just renderman jargon for a sphere

Well sure....but look at the light. the opengl widget is even hemispherical. And ps, this aint renderman.

It's not RenderMan, but it _is_ Pixar. We must all conform to the USD definition of the behavior for a UsdLuxDomeLight, which has it behaving like a sphere, not a hemisphere. The guide geometry in the viewport being a half sphere is something that could be debated, but if we made it a whole sphere it would look like a "sphere light". At least this way the geometry looks like the "name" of the light type...

OK, I see. Wow, there's so much strange, legacy terminology in renderman. It's a shame the whole industry is bending to that. Developers should be seeking to eschew obfuscation, not reinforce it. This just makes crews slower and shots more expensive.
