ok, I tried that, but all I get is a black square
At least before I had a Maya logo.
Maybe it's something I did different, in step 5 you say to draw a marquee, and then go to step 6, but when I do step 6 the marquee I drew disapears and I get a message at the bottom on the render view saying: "select a region and drag it to a swatch in Hypershade" and so then I draw a new marquee and then middle-mouse-button drag to the top of the shader that I used (under "Shader Library") and the the icon for that shader changes from "Maya" to just black :/
Did I do something wrong?
