Hello, and thank you again - I'll certainly go with that solution.
I got the feeling part of your previous message may have been cut off, unless I'm simply misunderstanding your position regarding customized shaders developed starting from your work.
The reason I'm asking is purely practical: while tinkering with your Glow shader, I seem to have stumbled upon an edge case. It appears that the shader multiplies the text color by the glow color, so complementary colors (for example blue text with a red glow) produce a black glow.
Not sure whether this is an intended behaviour or merely something I found out by chance. In any case, I may end up needing a different behavior altogether (either color mixing or a glow that is independent from the text color). My intended use is to use faint glows to alter the perceived color temperature of the text and visually convey warmth, affection, coldness, or discomfort.
Should I end up modifying or extending that behavior, I would still credit your work as the source material that inspired mine. Naturally, maintenance, debugging, and responsibility for issues introduced by my modifications would be entirely my own.
PS - Sorry for using your comments section as an impromptu support ticket. I couldn't find another way to contact you.
