Backplate/Env Map Functionality Broken in 5.10-RC1
Some 5.10 updates have broken the ability the feature to use an environmental map as the lighting in OSPRay pathtracing, while using a static backplate. This was a feature that my company Corvid paid to have implemented in 5.9, so the request is to get that functionality operational again.
