The parent `_validate_property()` wasn't called, which led to shadow
properties being visible even if shadows were disabled on a
DirectionalLight3D node.
* Made the Basis euler orders indexed via enum.
* Node3D has a new rotation_order property to choose Euler rotation order.
* Node3D has also a rotation_mode property to choose between Euler, Quaternion and Basis
Exposing these modes as well as the order makes Godot a lot friendlier for animators, which can choose the best way to interpolate rotations.
The new *Basis* mode makes the (exposed) transform property obsolete, so it was removed (can still be accessed by code of course).
Some split distance properties are unused depending on the
current shadow mode. Also, Blend Splits can only be used if the shadow
mode is PSSM 2 Splits or PSSM 4 Splits.
This also moves the Fade Start property to be located after the
split properties. This avoids intertwining "conditional" properties
with a property that's always available.
Roughly based on https://github.com/godotengine/godot-proposals/issues/3375 (used format is slightly different).
* Implement bitwidth based animation compression (see animation.h for format).
* Can compress imported animations up to 10 times.
* Compression format opens the door to streaming.
* Works transparently (happens all inside animation.h)
This can be used to improve 3D shadow rendering quality at little
performance cost. Unlike the existing Hard setting which is limited
to variable shadow blur only, it works with both fixed blur and
variable blur.
* New track type BLEND_SHAPE
* Blend shapes are imported via this new track type
* Processing is more optimized (no longer relies on variants)
* Modified the Blend Shape API in MeshInstance3D to use indices rather than StringNames (more optimizes)
* Promo: Fixed a small bug in gizmo updating in Node3D that affected performance
Dedicated BlendShape tracks are required for both optimization and eventually implementing them in animation compression.
* New plugin system to control the whole import workflow
* Can add options and run code at every import step (general, per node, mesh, animation, material etc.)
This constitutes a first version of these plugins. The ability to interact with the import preview dialog will likely be added later on.
