https://forums.autodesk.com/t5/3ds-max-forum/reverse-p-flow-to-collapse-inwards/m-p/9249297#M27445 <P>I want to make a particle system where the particles move inward instead of outward, like a particle bomb but in reverse, but I'm stumped on what forces and modifiers to use. So far, reversing the speed modifier hasn't worked, neither has a gravity force, but I'm not sure I'm doing it right.</P> Tue, 14 Jan 2020 12:18:06 GMT Ryawy 2020-01-14T12:18:06Z https://forums.autodesk.com/t5/3ds-max-forum/reverse-p-flow-to-collapse-inwards/m-p/9249297#M27445 <P>I want to make a particle system where the particles move inward instead of outward, like a particle bomb but in reverse, but I'm stumped on what forces and modifiers to use.
