Changes to reduce the latency between changing node selection in the editor and seeing the new node reflected in the Inspector tab
- Use Vector instead of List for ThemeOwner::get_theme_type_dependencies and related functions
- Use Vector instead of List for ThemeContext::themes, set_themes(), and get_themes()
- Add ClassDB:get_inheritance_chain_nocheck to get all parent/ancestor classes at once, to avoid repeated ClassDB locking overhead
- Update BIND_THEME_ITEM macros and ThemeDB::update_class_instance_items to use provided StringNames for call to ThemeItemSetter, instead of creating a new StringName in each call
These changes reduce the time taken by EditorInspector::update_tree by around 30-35%
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.
The `PROPERTY_USAGE_READ_ONLY` flag only makes the property read-only in the inspector, but the property also has the `PROPERTY_USAGE_NO_EDITOR` flag which means it won't show up in the inspector. So it does nothing, while still making it editable from scripting.
To make it read-only for scripting too, this PR removes the setter from the `PropertyInfo`. And since the `set_capture_included` method is now unused, it was also removed.
When UVs are mirrored in a mesh, collapsing vertices across the
mirroring seam can significantly reduce quality in a way that is not
apparent to the simplifier. Even if simplifier was given access to UV
data, the coordinates would need to be weighted very highly to prevent
these collapses, which would penalize overall quality of reasonable
models.
Normally, well behaved models with mirrored UVs have tangent data that
is correctly mirrored, which results in duplicate vertices along the
seam. The simplifier automatically recognizes that seam and preserves
its structure; typically models have few edge loops where UV winding is
flipped so this does not affect simplification quality much.
However, pre-processing for LOD data welded vertices when UVs and
normals were close, which welds these seams and breaks simplification,
creating triangles with distorted UVs.
We now take tangent frame sign into account when the input model has
tangent data, and only weld vertices when the sign is the same.
