sorry tpt.el.prti.falldown=1 and =2
You can write in console to prti powder tpt.el.prti.gravity=1 tpt.el.prti.dalldown=1 tpt.el.prti.hardness=0 and to liquids tpt.el.prti.gravity=2 tpt.el.prti.f
Already rejected, plus this can be done with existing things so it is pointless
I wish this was an element... it its turned off would it let particles move through or block them?
