Self-explanatory. These options have no effect on particle density. Instead, I can change the individual particle's multiplier, but it only accepts integers, hence no way to make particles be in lower quantities (making MORE particles to appear works, though).

this is an unintended intended thing its due to the fact im using an integer for that setting will likely change that soon

Good to know! Thanks

at the very least i've fixed the search radius thing if im not mistaken the non integer modifier values are turning out to be a bit of a nightmare

That is correct.
For what I've seen by messing around some options on the newest version, search radius works with some particles (like soul storms) but not on others like rain or snow. Non-integer modifier values like 0.8 just makes said particle disappear.

Oh, I see!
For some reason I didn't make the connection. Particle distance options in general would be a godsend.

eventually i will put that in dunno when tho

Thanks for the updates on this issue after so long. Looking forward for the change.
