Previously, vertex cache optimization was ran for the LOD meshes, but
was never ran for the base mesh or for the shadow meshes, including
shadow LOD chain (shadow LOD chain would sometimes get implicitly
optimized for vertex cache as a byproduct of base LOD optimization, but
not always). This could significantly affect the rendering performance
of geometry heavy scenes, especially for depth or shadow passes where
the fragment load is light.
Normal raycaster makes LOD generation process >2x slower and often
generates normals that look significantly worse compared to what the
simplifier comes up with by default. This was likely different before
last meshoptimizer upgrade, as the attribute metric was not functioning
properly, but now it looks like it's doing more harm than good.
This change makes it disabled by default but keeps an easy option to
re-enable it per mesh using LOD parameters for now until we get more
confidence and can remove the code outright.
Because the long term plan would be to disable this feature entirely,
the scripting API isn't changed, and it's just off-by-default there with
no way to re-enable.
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
