not quite real..

try to add a circle and then a red glow layer effect, then save that image as TGA with alpha map, and a red glow will mix with the background (usually turned white when exporting the TGA) and the final effect wont be the red but a mix with red and white. same for shadows.

I can explain better if you want:


on the picture above, i created some circles, one with a black color for the background color, and then transparent and then red, and added to the circles the same glow effects.

after exporting to TGA, and importing the picture to game studio, this is the result:


As you can see the A is almost what we want because we used blackcolor , but B is the perfect one, because we used a red color background, that matches the glow color we used, and the color is just there, and the alpha map do the glow transparency effect.

the other methods^(using tranparent layer) and using blacklayer turned to be imperfect.
Note that the transparent layer, mixed the red glow with some white as you can see on the picture! thats why a psd reader would be useful, but you guys keep saying no. its ok, just more work on photoshop and everythime we want to use layer we need to paint the background acoording the the color we want to glow -.-
