So the easiest way is this. I zipped up all five materials and uploaded here to the forum. You must save as ToVexiphne.zip - remove the .doc at the end.

Yes the last two are just #3 with bump. You get the idea.

You will find that #3 is exteremely sensitive to viewing angle - either tweak your camera position/angle, or you can adjust numbers in the shader.

The Math:Gain Value_2 controls the falloff zone size inversely - the closer that number is to 1 (.9, .95, .97, .99, .999 etc) then the tighter the falloff zone is.

The Math:Pow Value_2 controls the location of the falloff zone within the general gradient produced by the Edge_Blend.

I use Pow instead of the Edge_Blend Attenuation, because the Attenuation internal function is not mathematically what I want most of the time.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
