Where is this material viewport in Blender 2.8 Beta? Sorry, i'm just a noob in 3d program, so i don't really know what to call this thing.





But do you happen to know how to display this kind of material in Blender 2.8 Beta viewport?
Too bad that you cropped your image so tight... The shading options you are looking for are to the right of the image you posted.
Move the cursor over to the right of the screen and click to make the options active.
