[BUG-230953] Mfacejaw rigging don't work

[sl-service-account]

What just happened?

In blender i've made a custom joint points skeleton, with mfacejaw bone dislocated, when i try to animate it in blender all is fine, when i import in Secondlife i get a bone rotation distortion, i've tried different bone poses, resizes, locatings, nothing changes.

What were you doing when it happened?

here the video, with sl import and blender animation: https://www.youtube.com/watch?v=OMxCkQ53mRw

What were you expecting to happen instead?

SL doesn't allow custom joints/skeletons like other MMOs.

You're stuck using the bento skeleton in-world, regardless of what you can pull off in Blender.

@Lucia Nightfire

Is not a custom skeleton, is the official one, with the correct bones with the correct names

As you can see in the image mfacejaw is correctly parented with mhead bone

as you can see in the video, if i add the mFaceRoot bone, i get more distortion in the animation, the jaw is dislocated, i've applied all transformations in blender just to be sure, and checked the joint points import in SL

Hello!

I am unable to reproduce this with the following test file I have created: chaser.zaks_mFaceJaw_offset_test.zip
If possible, give this a try and see if it also exhibits the same behavior. You can upload these for free on the testing grid.

However, I think the issue might be casing. Be sure that the bone's name is exactly "mFaceJaw". "Mfacejaw" will not work.

Hi MaxTux,

You are reporting this against a third party viewer. Does this issue reproduce on the official Second Life viewer?

Please review all the comments above and see any of the additional advice helps too.

Thanks!

@Kyle Linden sadly linux official viewer is not updated :(

anyway i fixed it, it's not a bug: the mFaceRoot vertex group must be included even if not weighted, you can close this report!

And sorry again.
