you could also just turn off air velocity by pressing y until you see “AIR VELOCITY: OFF”
@cracker64, hmm, so air pressure is different then air velocity? I had always assumed they were the same.
SebasSmits:
if youre annoyed by the flying particles (like you want to extiguise fire with water but the water flies upwards) you can press the = button. when you press this button all the pressure and velocity will be erased.
i am not annoyed by flying particles
Also, i think concrete is one of the strange powders in TPT.... It isnt heavier or lighter than anything. I think it doesn`t go though because dest is normal the heaviest or some and concrete is the strange element so it stays on the concrete
