How to override a particle sprite ? 2005-04-24 - By ker.boris

Hi,
If you have an alpha channel on your sprite image, you should have your
matte.
Anyway, if you still want to override the sprite image (which I apply as a
simple texture image plugged in my Particle Billboard), you have to dig deep
in your Cloud / Particle Cloud / ParticlesOp/ PType/ Renderer / Particle
Billboard and choose the color parameter.
Hope this helps
