I have a 3D model of a character with cloth physics hair, I bent him over to see if the physics looked ok and all worked well it seems except I cannot figure out why it seems the collider of the mesh is stuck in some way.


its like the mesh animates but the collider that is assigned to the mesh is static, I couldn't find anything anywhere about this specific issue. if elaboration is necessary shoot some questions, thank you.

  • $\begingroup$ Are the modifiers in the correct order? Armature (top) then Collision (bottom) not vice versa. Or do you have a backup copy of the body mesh? $\endgroup$

  • $\begingroup$ @Blunder yes Armature is above collision, although i do have solidify and subdivide following those $\endgroup$ Jun 19, 2023 at 23:03

It is because the collision is computed before the rig deformations are being computed.

Modifiers in Blender are non-destructive and sequential. Which means the order in which they are placed matter. That's also why you have the option to move modifiers around in the modifier stack.

In your blend file, the Collision modifier is on the top of the stack which means it is computed first meaning the physics are calculated without considering the deformations from the rig :

[modifier stack1

To correct that, just drag the collision modifier below the armature modifier :

modifier stack again

With the colision on top of the armature modifier :

Wrong order

With the collision below the armature modifier :

Right order
