Help Strange sagging behaviour

[josemendez]

Hi Matty!

When the attached object is aset to non kinematic this doesnt happen. When I reduce the mass scale of the rod, the issue reduces, but this negitively affects my simulation,

This sounds like the rod is colliding against the object it is attached to. An rod cannot simultaneously be inside and outside some object so, as a result, the rod can't decide whether to keep intersecting the object (what the attachment "wants") or to project itself outside (what collisions "want") so it takes on the shape that minimizes error for both conditions, which is usually undesirable.

I tried adding another control point close to the end of the rod as mentioned in the attachments page of the manual,

If you don't set the control points' collision filters properly this won't help at all. The solution (using collision filters to disable collisions between the attached end of the rod and the object) is also described in the manual, see "attachments inside colliders":

let me know if you need further help,

kind regards
