Point Size Based On Camera Distance

[cah8222]

Does anyone know how to create particle points size based on the camera distance?
I do appreciate if someone can help me out.

in z of the camera projection or simply dstance form camera? not thet i really matters that much they do allmost the same thing.

I think so.
And could you tell me how to do it? How to create the particle points size based on the z of the camera projection or simply distance from a camera?

Thanks

Make per particle expression. That either transforms points to cam space or uses mag(particle.worldPosition-camera.wrorldPosition). The alter si offcourse much simpler because thats exactly what you write.
