I like the new 2.8 icons. Somebody did a really great work. But still not perfect in all cases. I suggest in the 3 icons related with rendering, to make a simile with traditional photography process.
1- the process of to chose the right photographic tape for your shoot
2- the process of transform the tape to the paper in laboratory
3- the final laboratory steps, like choose the best paper shoots
Because, more or less, that steps still match with 3D art process. Hope you like this proposal, thks
