Hi! I actually work on some underwater shots, and have created
a simple sphere volume emitter with instances pointing to the camera.

the camera has a fulldome lens attached and is placed in the center of
the emitter. a volume field kills particles near the camera (do not
get extreme huge planctons on screen)

that works fine for stills, where the camera isnt moving. but i have
some shots, where the camera is following a submarine,… and the movement
is very long. instead of creating a field of millions of planction it
would be great to find a solution, where just the plancton surrounding
the center camera is visible.

do you have ideas, how to solve this problem?!?

thanks alot for your time & Help!

Just thinking out loud here, but maybe use a distance node to drive the visibility attribute of your objects?

Could also set up a LOD system to swap out your objects with low poly stand-ins.
