During the import process, many importer nodes are replaced with their
engine node counterparts. For example, ImporterMeshInstance3D is
replaced with a MeshInstance3D node. Any meta data set on these
importer nodes, i.e. through a GLTFDocumentExtension, are lost during
the conversion. This change copies over any meta data set on these
importer nodes to their engine counterparts.
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.
Adjust the logic for position and scale animation tracks in the Apply Node Transforms case
To match how we adjust bone pose/rest, use basis.orthonormalized() for parentless bones.
* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
Random-access access to `List` when iterating is `O(n^2)` (`O(n)` when
accessing a single element)
* Removed subscript operator, in favor of a more explicit `get`
* Added conversion from `Iterator` to `ConstIterator`
* Remade existing operations into other solutions when applicable
Use a gradient sky to improve visibility in shaded areas,
while also helping the user orient themselves. The bottom of the sky
is black, while the top of the sky is white.
This change also makes it so that the Default Clear Color project setting
no longer affects the Advanced Import Settings dialog.
Both bugs were related to how position animation tracks were adjusted in rest fixer.
First bug: motion scale is applied before subtracting the origin when applying bone roll
Second bug: armature scale was lost when converting basis to quaternion, leading an unscaled position offset to be added to the scaled origin.
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 `rest_pose/external_animation_library` advanced option to replace bone rest with an exported Animation before retargeting.
Together this allows a purely importer based workflow to transfer a known good pose from one FBX to another.
