Re: Envelope Operator funkyness

[Sergio Mucino]

Thanks a lot guys! Set Reference Pose fixed it. I'm not sure how the pose could have changed, since as I said, these nulls are created by a script, and they are cluster constrained to a mesh, so I would not be able to move them. Anyway, the problem seems to be gone. Great! One more new thing learned today :-) . Cheers!

Also, doing a “set reference poses” should alleviate this, I think you must do it on the deformers (bone elements) and skin.

Select the mesh Envelope > Reset Actor. Watch for a shift of one of the nulls. One probably has moved for some reason. If your nulls are in a good place where you want them, you can use the current positions of the nulls for the bind pose but selecting all of them and doing a Envelope > Set Reference Pose.

The mesh shifts a bit right away (no need to go through the weights editing step). Could it be related to transforms stored in the nulls I'm using to deform the mesh? I don't see how something like this could have been introduced, since all nulls were created by a script... anyway, just exploring all the options. Thanks for any help!

I've got a quite complex mesh that I'm enveloping to a set of nulls. Everything is ok. I then do a Smooth Envelope Weights on the mesh, and then maybe tweak some weights using the Edit Weights table. Once I'm done, if I take the Envelope operator and mute it/unmute it, I can see the verts of the mesh shift positions. Sometimes (on other meshes) its by a super tiny bit. Other times (as in this mesh) it is more noticeable. I was wondering why this would be. Am I doing something that somehow disturbs the "rest shape" of the mesh stored by the operator (if it is that way how it works)? Can this cause problems down the road? Can it be prevented? Thanks for any comments! --
