How do I render particles with constant screen space size?
I would like to generate particles that render onscreen at a fixed size, regardless of its current distance from the camera, in a manner similar to screen space size material billboards. Although I would prefer to do this, per emitter, inside the particle system, I would not be opposed to a blueprint solution. Any help would be greatly appreciated.

A while back I made a material function that can change the size of a regular sprite particle depending on camera position and its distance to the camera:
I am sure that with some messing about you can get it to work the way you want it. (output goes into world pos)

If there is no such option in cascade, you can use material WPO to maintain fixed particle screen size.
