Thanks @doug_walker ! I thought it would be interesting to do a recap and see if we can come if some Zach/Chris’ mix of suggestions.

It is true that it is difficult to agree on naming conventions. For the record, the list I have written above is inspired by Substance Designer, Substance Painter and The Foundry Mari. And if we wanted to focus on the lowest common denominator, we could remove Height, Displacement and AmbientOcclusion (hence the optional tag).
Update : Due to popular demand, Displays P3 are back into this proposal. Thanks !
Thanks,
Chris
