I often need to update my assets for a specific job within certain lighting conditions; textures, shading, complex nodes etc. Eevee doesn’t support all the Cycles stuff (O-N/DisneyDiffuse, Aniso, Sheen, Bevels), so it can’t show all the nuances. But switching to Rendered/Cycles, it changes to World, which usually consists of a “boosted sun HDR” for a long time. Due overexposure, I need to either switch to world nodes and tweak the output or go to camera and tweak the exposure.
What I’d like to be able to do, is simply activate LookDev Eevee or LookDev Cycles, where the current Eevee world settings are being used (HDR, rotation angle, mirrored). It allows quick comparisons between the outputs, and quick checks if something breaks in Eevee for lack of support or shader compiling reasons (complex box mapping produced pink for me today after 2 min compile, but Cycles renders fine and all complex inputs going into the box mapping works on their own, and simple inputs also works fine).
Is this something we should ask for? Would it be useful for you? And would it even be possible without any major issues?
