Assimp mesh missing bones

I'm working on skeletal animation and got stuck on this really weird issue.

Using ASSIMP to import a .dae model.

I have loaded the model's bone hierarchy (nodes), but the mesh->mBones contains only 10 bones, while there are 29 total. I thought there are only those which are active during the transforms, but nope, that is not the case. Active bones are missing.

When reading the scene, I'm using aiProcess_ValidateDataStructure Importer throws no errors.

The exact problem is I don't have all the aiBone structures needed to obtain bone weights. Is it bad exporting or something else?

I'm attaching the object model and the scene. Thanks for all help. https://skfb.ly/CDIu

Solution

  • The problem turned out to be the biped system.

    Raw bones work just fine!
