TIL about shading, and am surprised how less I've seen this term in grading tutorials. While different, I feel like shading is something that should be learnt before grading.

PS You might have pasted two different answer drafts above. Paras 1,4 and 2,5 deliver similar information

They don't do that anymore, at least not for me. I tried contacting two different support agents and both mentioned that the functionality has been removed for them by the higher-ups.
