Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
- Skin groups now merge more cleanly together
- Skins whose highest nodes are siblings of another skin now get merged also
- Skin nodes who have children of another skin now also fuse together
- Removed the re-rooting of IBM code, as it is no longer needed with the Skin system
1: Depth draw mode set for transparent materials (iFire)
2: Skeletons
- Bone names now unique and seperate from scene names
- Due to mixture of fake joints and joints, new bone sanitizing for names added
- Fixed an issue where some disjoint skins were not being joined due to a logic error
- Deterministic and Depth-first bone creation order
3: Skins
- Removed duplicate skins when possible
4: Animations
- Fixed invalid morph target names
Condensed some if and ERR statements. Added dots to end of error messages
Couldn't figure out EXPLAINC. These files gave me trouble: core/error_macros.h, core/io/file_access_buffered_fa.h (where is it?),
core/os/memory.cpp,
drivers/png/png_driver_common.cpp,
drivers/xaudio2/audio_driver_xaudio2.cpp (where is it?)
Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.
It seems to stay compatible with formatting done by clang-format 6.0 and 7.0,
so contributors can keep using those versions for now (they will not undo those
changes).
Existing code only did the reparenting when the parent node was a bone. This
change fixes that, plus the reparenting code itself, which used the index of
the skin instead of the skin index itself to address the skeleton array.
To follow the glTF 2.0 specification in all cases (including outside
of imported glTF scenes), the blue channel is now used for metallic
and the green channel is now used for roughness.
This fixes https://github.com/godotengine/godot/issues/20377 , where blend shape scales the mesh if the mesh is also skinned.
The issue was that the blend shape was trying to blend using BLEND_SHAPE_MODE_RELATIVE (directly adding everything in morph shape as displacement), while bone weights were copied in the morph shape, which resulted in 2x bone weights causing mesh to become bigger when blended.
Setting the blend mode to BLEND_SHAPE_MODE_NORMALIZED while guaranteeing the data is correct fixes the issue (previously treating gltf2's morph displacement data as blend target data). Ideally we still want to use BLEND_SHAPE_MODE_RELATIVE since it may need much less data, but that seems to require a larger refactor?
