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.
When importing images, we store a compressed version of the image to a .ctex file with ResourceImporterTexture::save_to_ctex_format. When importing many large images at once, this can use a large amount of memory, especially when the .ctex file uses WebP format.
This change is for ResourceImporterTexture::save_to_ctex_format to use the original Image object instead of p_image->get_image_from_mipmap(0), to avoid creating a copy of the full uncompressed image when looping through the base Image and mipmaps. This reduces the import memory usage for large images by around 10% when using WebP, and 35-40% when Project Settings/Rendering/Textures/Lossless Compression/Force PNG is enabled, may vary depending on the image and number of import threads running. Same change applied to PortableCompressedTexture2D::create_from_image, which has similar logic.
This helps with #92084, but does not fully resolve the issue on its own, as compressing with WebP on many threads can still use a large amount of memory - this just lowers that amount, and makes it more likely that enabling "Force PNG" will reduce memory usage enough to import the files.
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
