I seem to recall trying to get a halo effect working in GG and I think Cybernescence or someone achieved this. Anyway, here is a pic showing a glowing halo around the FPSC classic Aiko character in red. I can post the effect file if anyone thinks they will find it useful.

Would be awesome if you could upload that, looks great!

cool, here you go. you can open up the FX file and change colour values on the following line and the :

//use this value to produce a color
float4 color = lerp( float4( 1.8,0.0,0.0,0), float4(0.0,0.0,0.0,0), angle );

the min/max angle values can be changed on these lines:

float MinLimit
<
string UIWidget = "slider";
float UIMax = 1.0;
float UIMin = 0.0;
float UIStep = 0.01;
> = 0.100000; -<<<<<<<< change this default value

float MaxLimit
<
string UIWidget = "slider";
float UIMax = 1.0;
float UIMin = 0.0;
float UIStep = 0.01;
> = 0.700000; -<<<<<<<< change this default value

I've named the file halored, but feel free to change it according to color. If you have darkshader, playing around with the values is even easier.
