Particles shrink as camera gets near?

[jebhardwick 0]

Hey guys! I've been searching around for this info but can't find it anywhere so maybe one of you wise owls can help.

I'm trying to find a way to have particles shrink to nothing as the camera approaches them, has anyone got any idea on how I'd achieve this?

Thanks in advance!

Use the distance function supplying the @P of the camera and the @P of the particle. Use the returned value to map it into a desired range which will be assigned to @pscale for the particle point.
