[HELP] Precise circular colliders

As we all know, Roblox’s collisions with custom meshes aren’t amazing and can be inaccurate. I’m creating something that needs accurate collisions for a circular hole but I cant seem to get anything to work. Any ideas? Thanks :3

Precise Colliders

Union (Even worse)

You can try making parts around it and turn collsion off the mesh/union then those parts invisible then it precise

Do you mean something like this?

yes but then you make those parts invis then use the union and then put it there with no collision then when the player jump down they will think it parfect collision

Hmmmm… maybe not. Now i have 841 individual parts to make up this collider, not including some more I’ll add later. Is there any other way to do this or any way to bring down the number of parts? (I should also add that these will all be moving slightly) :<

Roblox’s base parts have perfect collision since they’re part of the engine. The best collision you can get is using PreciseConvexDecomposition in the CollisionFidelity property.

Yeah, but like in the picture in the original post above that still isn’t gonna work.

I managed to get the part count down to 312 which should work for now :>

you could do something like this which is probably more porformaetnt

Wedges:

Wedges can provide less parts (they also align almost perfectly)

You can fill around it with parts

Actually, it’s probably possible that you don’t even need a union because of how perfectly these align
