Additive material for particles

[gagui]

Hello.

I'm just wondering if there is any way to render particles with additive materials.

Thanks!

You can kind of fake it by making a vex node which flattens all your particles to camera Z = 1.0 then use pcfind to color each point based on their close neighbours (pscale). You can weight them by some function for better quality. Then write the self illumination value to an attribute. This will work in any renderer. You’ll need a second wrangle to restore the original P
