Normal ramp shaders - how to affect alpha?

Support Basics & Interface

Hi guys,

I’ve been doing some stuff with ramp shaders recently, and wanted to have a mesh that was transparent in the main, but on the edges it becomes more opaque, and coloured. Therefore, I’ve been using ramp shaders with the Normal input specified. The problem is that the ramp shaders don’t seem to add to the alpha, so if I make the object have alpha=0, and the ramp shaders have alpha=1, it’s entirely transparent still.
Any ideas how I could do this?

the alpha in the ramp is how much the ramp color applies, not the transparancy of the material
to do what you want, use a spherical blend texture , map it to normal, use x and y mapping but not z, and set it to affect alpha
