Model converted by x3d-tidy views correctly in Sunrize, but not CMV
Please try to view this model in castle-model-viewer or report problem with model.
I’m trying to get this model viewing in general (beyond Sunrize). I don’t know if it validates yet, so please be patient as I do that sometime today.
It should pass castle model viewer checks.
https://github.com/coderextreme/HAnimUtilityKit/blob/main/WalkingAlienFinalOutputX_ITE.x3dv
Thanks!
The viewer doesn't report any problem, and castle-model-converter --validate WalkingAlienFinalOutputX_ITE.x3dv goes OK.
However the animation looks very weird / buggy. I understand the animation is correct in Sunrize, so this requires investigation -- and may be some bug on our side.
Thanks for your efforts, and Joe thanks you, too!

Maybe try some of the other animations in the file to see if they are better.
I understand that not all Joints probably have the exact right DEFs, but AFAIK, that didn’t stop me before.

One important point is, this is the only .glTF model I am converting. I can try converting more .glTF models with Holger’s x3d-tidy. Maybe that might narrow the issue?
I might have some old models here, on my old machine:
https://github.com/coderextreme/HAnimDecoratorAssembly https://github.com/coderextreme/HAnimDecoratorAssembly/blob/main/convertGramps.sh /
They are huge, compared to WalkingAlien.gltf. I can set up GItHub LFS and check them in.

It appears that this model has only translations, no centers for Joints!
I will work on a translation to center mapping.

The translation to center mapping works, plus I default translation and rotation in HAnimJoints.
It is a valid bugreport -- if the animation works in Sunrize and doesn't work in Castle Model Viewer, that's something I'd like to fix.
I saw that the testcase linked in the description https://github.com/coderextreme/HAnimUtilityKit/blob/main/WalkingAlienFinalOutputX_ITE.x3dv is no longer available, it was deleted from the repository. But I can find it looking in repo history, at September 1st, https://github.com/coderextreme/HAnimUtilityKit/blob/2438ee5a90356986ede911807ea7082661a8b503/WalkingAlienFinalOutputX_ITE.x3dv .
So, please leave this open. I will want to eventually investigate it. Sorry it takes time, there's too many tasks I try to do :)
Possible reason for failure: model from https://github.com/coderextreme/HAnimUtilityKit/blob/main/WalkingAlienFinalOutputX_ITE.x3dv relies on HAnimHumanoid.jointBindingPositions, it has:
jointBindingPositions [
0 0 0,
0 0 0,
-0 -82.478 -1.859,
-0 -89.597 -3.1794,
-0 -93.79 -3.1975,
-0 -97.766 -2.832,
-0 -103.1 -2.2463,
...
And we don't handle HAnimHumanoid.jointBindingPositions yet.
I will look into fixing this soon.
