Help Reduce rope movement?

Of course, I think I see the issue. My test environment is made up of probuilder shapes which are mesh colliders.

If a particle starts a frame the wrong side of a MeshCollider's surface, it will stay there as MeshColliders have no concept of what "inside" or "outside" means. They're just a paper-thin surface, that prevents other objects from penetrating in either direction. This is because outside/inside tests for arbitrary concave meshes is quite expensive.

Primitives (being convex shapes) do have a inside/outside concept and can project other objects outside if they start the frame inside of them.

It mainly occurs when the player spawns in, as the rope is attached to their hip, which begins at floor level causing the particles to embed underneath the surface collider as you said.

Best fix would be for your character to spawn with their feet at floor level, then. If your character is a capsule collider, I think you also risk him falling trough the floor otherwise.

Let me know how it goes!
