Neon glow, alpha channel help

Questions & Answers
1

I’ve spent the better part of the weekend trying to figure this out.

Simply, I’m trying to recreate that Tron look; simple glowing edges, almost wireframe like. Think tron/vector line games.

I seem numerous references to alpha channels, and glow, however I can’t make sense of this. How do I edit an alpha channel? ( I assume Photoshop) I have Unity Pro, so am able to use all image effects.

Whats the best way to replicate this effect?

Thank you in advance

There is an excellent article about that on Gamasutra (by the developers of Tron 2.0, actually :))

The article is already a couple of years old; I guess nowadays you’d combine it with HDR lighting. The whole thing is a fairly advanced topic. Learning shader programming certainly takes more than one weekend :slight_smile:

Alpha channels can be created and edited in any decent image processing program. Photoshop is the choice of most professionals but Gimp works just as well.
