Previously, _asset_parse_skins() would mess with the order of skin indices.
However, the rest of the code expected these to match to ufbx skin indices.
To fix this, retain the original skin indices in FBXState::original_skin_indices.
Turns out that the information in FBX Pose objects is relatively often broken.
Using skin cluster bind poses seems more reliable, but cannot capture the bind pose of the root bone.
Set p_scene_parent to the skeleton to guarantee BoneAttachment3D nodes are added as a child of the active skeleton.
Use get_owner() to go all the way up when calculating the root node in generate_scene
Adds a bool import option `nodes/import_as_skeleton_bones`.
This is supported in all FBX or GLTF document based formats.
It is especially useful for retargeting and importing animations.
This update introduces a new import method for FBX files using ufbx. If the fbx2gltf import fails, it will use the most recently cached scene from the ufbx import. The process is sped up by introducing threads to load the ufbx portion.
Key changes include:
- Support for importing geometry helper nodes in FBX files.
- Addition of cameras and lights with updated names.
- Removal of the fbx importer manager.
- Introduction of ModelDocument3D and updates to its methods.
- Changes to FBX import options and visibility.
- Updating the documentation and handling some errors.
- Store the original non-unique node, mesh and animation names in FBX and glTF.
