Unable to edit pre-posed mesh and re-bind without warping

[mfastabend]

Hello,

I am currently editing an asset pack I bought from the Unity Store. I have encountered an issue where one of the character meshes is imported pre-posed. When I unbind the mesh it returns to its neutral pose, but the rig does not follow. So when I re-bind it, there's warping and the skeleton is mismatched to the mesh. I have tried zero-ing out all of the rig's rotations afterwards but it doesn't assume the neutral position. If I do this while the mesh is still bound, the entire thing gets crumpled as well. I will attach a scene file so that you can see what exactly is happening. The most notable deformation when the rig is re-attached is the right claw.

Thank you,

Hi there!

This often happens with rigs that were built into a model that hasn't a good pose, since the joint chains are created with a good orientation and then rotated into the mesh while skinning, so there are rotations on the joints in the bind pose. Also in this rig there seems to be odd translations in bind pose as well, so it isn't really a good rig...

If you want to have the rig without the pose, you can select the root joint and then use the "Skin-> Go to Bind Pose" command to reset the rig into the bind pose.

make sure to do that on a frame without a keyframe, so you can keyframe the joints in bind pose and reset the rig into bind pose if you need to unbind/rebind for some reason.

I hope it helps!
