As you start adding more and more nCloth elements in your scene, the performance…will start to degrade pretty quickly, and you'll need to take some special steps…to improve the performance.…Here I've got six flags, and they're all sharing the same nucleus node, and they…all have the same settings to their nClothShape nodes.…And when I play, you will see that we're getting approximately 10 frames per second.…But we can improve this, and we can get closer to real-time playback by using…something called collision layers.…
We can set it up so that certain objects are not allowed to collide with other…objects, and that would help with performance, because it would reduce…unnecessary calculations.…For example, none of the flags are ever going to touch one another, so it'd be…a smart thing to disable the ability for the flags to collide with one another.…Likewise, each flag will only ever be able to collide with it's own flagpole, so…we can make it so that this flag won't collide with any of the other flagpoles.…
