[BUG] Exported models with GLTF / GLB broke the animations.

[MrScautHD]

What are you trying to do, and what do you expect to happen?

Loading the model into model viewers, and played the animations. (like this: https://sandbox.babylonjs.com/)

What happens instead?

But the model starts to brake:

Instead of:

It looks like this:

@JannisX11 already fixed?

[MrScautHD]

It looks like the animations get mixed

Could you test if this is still an issue in the 4.10 beta? https://github.com/JannisX11/blockbench/releases/tag/v4.10.0-beta.1

Still broken :(

[MrScautHD]

@JannisX11 is it still an issue?

[JannisX11]

I am not sure, I have tested a few models during beta and haven't run into the issue since. If you can still reproduce it, please share the model and configuration so that I can recreate it on my end.

[MrScautHD]

@JannisX11 Here is a model build with the latest Blockbench version:
Player-Female-new.zip

[MrScautHD]

And here are the arms up

it looks like the animation blending in one.

That is how it should looks like:

[JannisX11]

Could you share the bbmodel file with the export configuration of an affected model so that I can try and reproduce it?

[MrScautHD]

@JannisX11
Player-Female.zip

[MrScautHD]

@JannisX11 do you found the error?

[JannisX11]

Yup, it happens because the arm bones have a 90 degree angle in edit mode. The armature animation doesn't handle that correctly. I'm working on a fix.

[MrScautHD]

@JannisX11 And what about the mixing of the Animations i mean in idle the hands move upwards, the feed is rotated wierd... Should that get fixed too?

[JannisX11]

Fixed 🎉

[glitch128]

has the site been updated yet?
edit: saw that it was pushed to patch, so no. the site hasn't been updated yet

[MrScautHD]

@JannisX11

Amazing work, thx.
But there a still some small issues

If you see one shoe is a bit more rotated down as the other one

But in blockbench it works fine:

Even for the arms:

In blcokbench:

But it looks like this happans when seting a diffrent animation like from walk to idle the hands working fine but by moving from run to idle the hands breaks. (Like the old pos of the animations not reset just get overriden)

[MrScautHD]

But i see right now the issue comes from (https://sandbox.babylonjs.com/)

Because with the windows model viewer it works fine.

[glitch128]

looks fine on https://glb.ee/ as well. maybe it's just a thing with babylon
