Cloth simulation randomly broke on my project

So I was trying to put a cloth on top of this grate for my scene, but cloth simulation just broke on its own, not colliding properly like so:

Before you say it doesnt have enough polygons, it does.
So, does anyone know why it does this? Did I accidentally bump a weird option or something?

  • Did you modify the cloth object after the simulation was assigned? Cloth doesn’t like certain modifications. You could try removing the cloth physics from the cloth object and re-creating them, it sometimes solves issues.

  • Make sure the normals on the obstacles aren’t inverted.

  • Make sure the “single sided” setting is active on the obstacle (it should be by default) and possibly try “override normals”. Those 2 settings can improve collisions.

  • Does any of the objects have modifiers on them that could modify their position or shape?

Ive tried redoing the cloth several times, so I dont think its got anything to do with a certain modification. Maybe the problem is in the grate, I’ll check.

Update: I tried every suggestion you gave and recalculating the grate’s normals seemed to fix the problem. Thanks!
