Unit test bee.glb is failing

[bertt]

When running test LoadModelsFromBabylonJs it looks like there is a problem on validating saved Bee.glb (TestFiles\BabylonJS-Assets\meshes\Bee.glb), there are validation errors like:

     {
                "code": "NODE_SKINNED_MESH_NON_ROOT",
                "message": "Node with a skinned mesh is not root. Parent transforms will not affect a skinned mesh.",
                "severity": 1,
                "pointer": "/nodes/111"
            },
            {
                "code": "ACCESSOR_ANIMATION_INPUT_NON_INCREASING",
                "message": "Animation input accessor element at index 58 is less than or equal to previous: 1.899999976158142 <= 1.899999976158142.",
                "severity": 0,
                "pointer": "/animations/1/samplers/0/input"
            },

that's interesting, I take it that BabylonJS has recently updated its test models?

The first issue is a warning that can be dismissed; nodes with a skin object override their own transform, so putting them inside a hierarchy is redundant and a waste of resources, that's why it's recomended for nodes with skin objects to be root objects.

The second is an actual error on the model file, the validator is detecting invalid time keys in an animation. Which is dangerous because it can lead to a division by zero error in models.

For now I can remove the model from being processed by the tests until BabylonJS fixes it.

I've reported it to babylonjs: BabylonJS/Assets#132
