What can we do to understand the subject when the question can be 2.8 (or not) and can be Eevee (or Cycles)?
I think all is said, except that the OP rarely (never) indicate this context.
Previously this was coming by itself: Internal or Cycles. In 2.8 I've not seen any indication about it.
Do you think this is a problem? If yes what can we propose to solve it?
(for information, I don't know which tag to set about it. Version? no, 2.8? no, context?... so 'discussion' will be the good one)
The OP indicates 2.8 but which rendering system?
