I am trying to make a node based editor window with the new GraphView UIElements that the new ShaderGraph is made out of. I've come quite far in understanding how the UIElement tree works and how the style sheets work and all that. I even have empty graph nodes appearing in my empty ShaderGraph. But my empty nodes are 1 pixel in height, and stretch the full width of the window. I cannot figure out how to get actual boxes for the nodes to appear that I can then drag around. I have been digging all through the ShaderGraph source with no luck. Has anyone managed to get a basic barebones node system working with the new ShaderGraph GraphView system?
