Area Light Issues:

Arnold: Geometry of area lights ignores the alpha of the applied texture.

Octane: Alpha on area lights is not applied to reflections in surfaces.

Octane: IPR may need to be re-loaded first for area lights to appear.

Redshift: Geometry of area lights ignores the alpha of the applied texture.

Mantra: Geometry of area lights ignores the alpha of the applied texture.
