This is useful for custom tagging of objects with properties (for example in Blender) and having this available in the editor for scripting.
- Adds import logic to propagate the parsed GLTF extras all the way to the resulting Node->meta
- Adds export logic to save Godot Object meta into GLTF extras
- Supports `nodes`, `meshes` and `materials` (in GLTF sense of the words)
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.
- GLBs produced by godot don't pass validation when there's no data in the buffer segment. The segment is dropped but the size of the chunk_header is still reported in total length (incorrectly)
- Remove empty "extensions" JSON object being appended to all nodes (if it's still empty). This is just cutting down on unnecessary bloat and consistent with the rest of the file's attempts to not emit any keys that are equal to their default value.
- Allow the case where root_nodes is empty. This is permitted by the GLTF spec. Moreover it can happen fairly naturally when using the ROOT_NODE_MODE_MULTI_ROOT root node mode on a scene with only a root node (which is valid in godot).
- Don't create an initial buffer until we're ready to write data into it (buffers of byteLength=0 don't pass validation).
* 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
- Added check for "animation/fps" key before attempting to use it in EditorSceneFormatImporterBlend::import_scene, to give error instead of crashing
- Don't show "Advanced..." button if last import used "Keep File" or "Skip File"
- Don't try to call ResourceLoader::load on kept/skipped file when changing importer, which would give an error
Fixes#90324
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
