This preserves compatibility when upgrading Godot 4.2 projects which relied on that
path being configured in the editor settings.
The old name also makes sense for this one, it's fine for fbx2gltf_path to be under
a generic fbx category which could have more settings also impacting ufbx.
ufbx has special logic to handle animation/trimming, and most users expect trimming to be on.
For existing projects, we should upgrade files0 to FBX2glTF to preserve node compatibility.
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
Reimplements "Remove Immutable" by comparing to the skeleton rest.
It is necessary to delay removing animation tracks until after the correct rest pose is calculated in rest-fixer.
Preserves the original implementation in the GLTFDocument / FBXDocument API for compatibility.
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.

This importer was the fruit of a lot of amazing reverse engineering
work by RevoluPowered, based on the original Assimp importer that was
introduced by fire.
While promising and well tuned for a specific type of FBX scenes, it
was found to have many flaws to support the many FBX exporters and
legacy models that Godot users want to use. As we currently lack a
maintainer to improve it, those issues are left unresolved and FBX
import is still sub-par in the current Godot releases.
After some experimentation, we're instead adding a new importer that
relies on Facebook's `fbx2gltf` command line tool to convert FBX to
glTF, so that we can then use our well-maintained glTF importer.
See #59653 and https://github.com/facebookincubator/FBX2glTF for details.
