Sorry for the confusing title, it’s past 5am and I’ve been at this for forever… so basically, without going into man specifics, this is my material setup (real dirty):
Now, you’ll notice that the preview is pitch black. However, if I hit preview on the Frag node, I get this:
How is this possible? Frag is the last node in the network. There is no change if I shift the UV1 and UV2 channels up, I use those to transfer color values, not UV values. In the screenshots a WorldPos node is plugged into UV0, but TexCoord doesn’t do any better either.
Anyone got any ideas what might be wrong?
