Hello again…

anyone?

thats a unity pro thing with the glow post fx for example
without pro its impossible basically without adding a lot of fake alpha extra geometry

Im using the Pro version…can you tell me how to do it?

the glow shader from the pro apps will do it given you created your textures accordingly (see the reference on how it works etc)

Found it…I use the Self-ilumin shader and then put Bloom and Flare image effect on my camera and get the result that i want.

thanks dreamora…

Looking forward to see what you create with it :slight_smile:

Skip to 23 seconds and watch, that’s all unity postfx glow (2.6.1 too, I imagine 3 may look even better)

Tron game you made with Unity!?

Yay :slight_smile:

What I realized to forget to mention: depending on what you want to achieve, also check out the shader replacement examples in the resources above, cause through that path you can potentially even achieve per object glow if desired (among other cool effects).

I could not get good results with bloom effects. The problem is that bloom always brighten everything. In Tron you just want to glow the blue and red stripes, but not specular highlights. My results are looking very “dreamy” - if you know what I mean. Is it somehow possible to just add the bloom effect to one layer?

I started by creating two cameras, one for the “non glowing things” and one for the “glowing things” - and applied the bloom for the last one. If I render the “glowing things” layer first and then the other layer the glow seems to be correct but its behind the objects. If I render the “Non glowing things” layer first and then the “glowing things” layer the glow gets applied for all visible pixels.

Im kind of confused how to obtain a real TRON-like shader with unity…

I also started with “Funky Glowing Things” Shader Replacement Pack - but this is not working on iOS.

Any one can help me out?

Bloom is based on the alpha channel of the render output. As you’ve discovered, specular highlights add to output alpha by default. However, you can change this behaviour by writing a surface shader with a custom lighting function that does not change alpha.
