* 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.
Dilate fills gaps that are caused by the rasterization. As dilate is based on
the alpha-channel which is not part of denoise, dilate can be run after denoise
as well. So that colors are not denoised/mixed over seams.
Dilate fills gaps that are caused by the rasterization. Previously denoise
was done before dilate which caused the gaps to become filled (non-zero). This
resulted that the gaps were not recognized by
dilate and the background color leaked.
This is fixed by executing dilate before denoise.
Whenever we change the name (or remove) generated cpp files with the `.gen.cpp`
extension, users run into build issues when switching between branches (i.e.
switching before and after the name change/removal). This is because we glob
`*.cpp` so if a now-obsolete file from a previous build is present, we'll
include it too, potentially leading to bugs or compilation failure (due to
missing headers or invalid code).
So globbing patterns in `add_source_files` will now skip files ending with
`.gen.cpp`, which should instead be passed explicitly where they're used.
Currently the method ray_hits_triangle determines triangles not to be hit by
a ray due to an epsilon that is too big. In practice those triangles are hit by
those rays.
This is fixed by introducing a smaller epsilon.
* 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.
We've had many issues with WebM support and specifically the libvpx library
over the years, mostly due to its poor integration in Godot's buildsystem,
but without anyone really interested in improving this state.
With the new GDExtensions in Godot 4.0, we intend to move video decoding to
first-party extensions, and this would likely be done using something like
libvlc to expose more codecs.
Removing the `webm` module means we can remove libsimplewebm, libvpx and
opus, which we were only used for that purpose. Both libvpx and opus were
fairly complex pieces of the buildsystem, so this is a nice cleanup.
This also removes the compile-time dependency on `yasm`.
Fixes lots of compilation or non-working WebM issues which will be linked
in the PR.
