Ok, slate is a great node editor (for me yes) but slot material is very slow and old system. It's use rendering to make a preview.
We need a realtime rendering fast the not make any block during editing or active shade render.
Arnold make some issue during editing material if it's on Active shade rendering. Many windows go down, disappears or block and slots not work properly.
Please, We need a good engine in all parts of software.
Thanks!
