Does PointMaterial Support Multiply Alpha Blending?

Right now i’m attempting to create a particle system. But the problem is though, that the PointsMaterial alpha transparency seems to go from 0 to 1, unlike SpriteMaterial. Also looking into the documentation, there’s no way to change the blending for PointsMaterial.

What can I do to create a particle system which uses Points and has blending? Or should i uses SpriteMaterial (or maybe try to learn ShaderMaterial).
Thanks.

The blending properties are documented in the upper class Material. The following points example changes the default blending to THREE.AdditiveBlending.

Ahh, thank you. I had misspelled the MultiplyBlending. (that’s why the parameter wasn’t found) I’ll go to the examples next time first. cheers
