Right now I’m using Blender 2.8 beta. I know how to apply the material for the object that I shape and deformed however I have difficult time to find node editor on new version of Blender. I’m lost and confused by the different interface from older version especially 2.79 beta. Please help!
Easiest way now is to go to the shading tab at the top of the screen. You can, as always make new windows to open a node editor, but I find the shading tab a nice and efficient way of applying and viewing materials.
