New to blender and have been digging into a lot of tutorials and trying to learn more about shaders and how they interact. I have a neon-like flicker effect on some text which is working well when the neon is on, but when the neon effect is off, it's leaving the curves black, which I would like to control better.
Steps to recreate - I created 3 text objects (osrius the - bear - pally), turned them into curves, extruded 0.01m and beveled 0.005m. The idea was to create round-ish tubes to be similar to neon (this may be where the issue is?) - When I add the neon flicker effect it looks like the first photo below, all of the colors are right, good emission and the flicker works as expected.
When the flicker effect is off - the curves are just sitting there black and I can't figure out how to control or change that (2nd image). I've placed them in a scene and rendered out a couple of rough drafts for animation timing, hoping they were just view window outlines, but that was a little too hopeful. I would like to figure out how to effect change to the off state of the neon effect. The ideal would be a semi transparent state, or just invisible when the neon is off. Any advice on where to start looking for the answer, a tutorial to look into, or an answer would be super helpful.
