Spawn rates / Spawn times

Hey, so I'm trying to figure out how to increase how many nodes spawn, and how quick they respawn. I can't figure it out though. I must've skipped over a plugin by accident, because I can only find plugins that edit how much they drop-like 2x, 3x multiplier plugins.

I also want to setup quicker crates/barrels respawn time but same with the nodes, I can't figure it out. I looked around on reddit, and found someone that said a command string worked, but didn't seem to work for me.

Anyone know what I can do?

Play whith these server parameters:

spawn.max_density
spawn.max_rate
spawn.min_density
spawn.min_rate
