Additive Animation not working with poses in BabylonJS 5

Bugs
1

Hi all,
some functionality in my app that relies on Additive Animation stopped working in Babylon 5. As a first step, I went to the Playground example for Additive Animation from the documentation and found that the two poses Sad Pose and Sneak Pose are no longer working in Babylon 5 but look correct in Babylon 4.2.

I’m guessing that whatever broke this Playground is also the root cause of my issue, because my app is doing the same thing, ie taking a pose and applying it as an additive animation on top of existing animation. Any chance someone could look into what’s going on? It would be much appreciated.

Hello, just checking in on this again. Hoping to upgrade to Babylon 5 ASAP and this is a blocker for us. Thanks!

@bghgary might it be related to the skeletal loading changes in 5 ?

This is caused by a change that we made to the glTF loader for the animation curve editor. Basically, the frames now default to 60 fps instead of 1 fps. cc @carolhmj

You have two options:

  1. Revert back to the old behavior by setting the glTF loader targetFps back to 1: https://playground.babylonjs.com/#6I67BL#296

    BABYLON.SceneLoader.OnPluginActivatedObservable.addOnce(function (loader) {
    loader.targetFps = 1;
});

  2. Multiply the animation hard coded values by 60: https://playground.babylonjs.com/#6I67BL#298

     sadPoseAnim.start(true, 1, 0.03333333507180214 * 60, 0.03333333507180214 * 60);

     sneakPoseAnim.start(true, 1, 0.03333333507180214 * 60, 0.03333333507180214 * 60);
