I want to do black smoke effect with ParticleSystem. I have not succeed in changing the color to black in the SMOKE example of the jmetest.effects.RenParticleEditor.
If I set the start and end color to black the smoke is completely invisible. Although the background is black, the white grid lines should not be seen through smoke.
I have also tried luck by changing the blend functions, but got only bad results like solid black rectangles with no alpha.
