I have seen this happen on multiple saves where a piece of stone/material falls through a 1-pixel wide shaft for a decent legnth of time.

science feature neat airspeed speed acceleration falling stone

Ah, I see.

Yes, collision handling is currently terrible. Hypothesis on the right is roughly correct. When a particle collides, all components of velocity are reduced by the same factor regardless of the shape of the obstacle. Brushing against something has the same effect on velocity as slamming straight into it. Air turbulence causes slight sideways movement, without air the particle just falls straight down.

It is air simulation because if you turn off air in the options they just fall normally

this is pretty strange. my idea is that the air in between the stone is being compressed and holding the stone up. congrats on your first fp save!

I like this discussion, but i think we need to remember to try to disprove these hypotheses, too. If you can't disprove it, then you might be onto something.

Do you guys like these types of saves? or should i stick with machines and systems?
