Looking to replicate the kinematics example showcased in this link:
https://threejs.org/examples/#webgl_loader_collada_kinematics
When using the collada file provided in the example, everything works perfectly. However, when attempting to use my own collada file, I encounter a "length" error at line 138 (using the exact same code for now):
https://github.com/mrdoob/three.js/blob/master/examples/webgl_loader_collada_kinematics.html
Does anyone have any insights on why this might be happening?
Based on a response I received on the Three.js GitHub, it appears that my DAE file lacks kinematic information such as library_kinematics_models or library_kinematics_scenes tags and only features a basic armature for skeletal animation. While I was aware of this fact, I had initially believed that the presence of kinematic data was essential for accessing joints and other related elements. As a result of the absence of animation data, I will be limited to displaying it statically using Collada Loader.
Edit: In cases where the loader identifies a skin and bone hierarchy, it will present the corresponding mesh as a SkinnedMesh within the children array (in my case, it was children[1]). This specific object includes a skeleton property that facilitates access to all bones.
Subsequently, you will need to generate an animation utilizing the Animation System.
For further details, please visit my discussion post on the Three.js discourse platform.
