Here’s a quick tip for how you can gain more control over your collision meshes, using Maya’s
Face Extract mechanism.
- Select some faces
- Face Extract, with
Separate Extracted Facesleft unticked
Ragdoll will then treat those extracted faces as its own collider shape, a.k.a. “island”. There’s no limit to how many islands you can have, so go nuts.
This is using the default
Islands decomposition mode.
The advantage to this over using the
Automatic mesh decomposition method is that (1) you get to pick where to slice your geometry and (2) there is virtually zero performance cost added on scene open. The Automatic method can take up to several seconds (to minutes!).
