Project from view using photoshop Im trying to follow this tutorial but using 2.8 and I can't seem to figure out how to get it to work.

I linked my photoshop via both the folder and the exe in the preferences>image editor 

I found the external button but I just ge this error

"operator bpy.ops.paint.image from view poll expected"

Any help?
Just incase anyone else needs this I figured it out, it only works in the stable release in Blender 2.8 and I was using the old version back in July

Link your image editor by going to Preferences > file paths > image editor > click on the EXE of your program

Then to project from the editor go into texture paint > Options > External > Quick edit 

Save to apply save the file, make sure you only have one layer it will mess up. Then hit "apply" under external.
