Planet simulations

So i've seen a lot of videos where particles look and act like planets floating and colliding in space. when i place particles they just float and don't attract eachother, they also lose any rotation i put on them so they just fall back into the center without doing anything interesting. i've activated node gravity but that doesn't seem to change anything. the controls are super confusing.

UPDATE: upon further testing and getting used to the game i've discovered that there appears to be a limit to the maximum amount of particles allowed before node gravity automatically disables, presumably to save on performance.
TLDR; i was adding too many particles.

it's true. Next version will contain FMM (fast multipole method) for gravitation that's allow much more particles with the enabled node gravity
