Is there a way to recolor a particle effect when only one texture, glow05, is used?
The easiest case, where the Particle can receive its color from the texture, is controlled using true/false in the PerParticleFog parameter:
true
followed by replacing it with the desired color specified by the effect's texture!
If everything is bad and the Particle contains "hardcoded" colors, then you can use any 16-bit editor to change the components of the color, i.e., RGB.
Here's how I implemented this for the creature Namtar for the NCF project!
