cell with colour correction for bumpmap 2005-06-14 - By Chris Marshall
Back
Thanks Holger.
One problem is that there aren't coords on a cell shader. Not to worry.
I might have a go with your BA_Cell.
The workaround I came up with was to have one cell node run through a
colour correction, then plugged into the colour 1 of another cell node.
Then the second cell is the one with bump checked on.
It's not ideal because obviously you're combining two cell nodes, but
the effect I was getting was more or less what I was after.
Cheers
Chris
