-When importing, a vertex-only version of the mesh is created.
-This version is used when rendering shadows, and improves performance by reducing bandwidth
-It's automatic, but can optionally be used by users, in case they want to make special versions of geometry for shadow casting.
Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆
Blendshapes without a skeleton already worked.
However, due to a faulty ERR_FAIL_COND, it was impossible to create a mesh with both bones and blendshapes.
This also fixes an assumption that all surfaces reference the same number of bones as surface 0.
* Support KHR_texture_transform.
* Support exporting glTF2
* Support exporting instanced scenes
* Extract into a gltf state and gltf document
* Add a tools menu for exporting gltf2
This makes it possible to view far away objects without
having to tweak any settings. This results in a more usable
editor when working on large-scale levels.
This change should have no impact on performance, but note that
Z-fighting will be visible at a distance. This can be made less
visible by increasing the Znear value (however, doing so will cause
nearby surfaces to disappear).
This change was also applied to the editor, but it will only
apply to newly created scenes.
This also changes the default camera settings in the glTF importer
to match the Camera node's defaults.
-Happens on import by default for all models
-Just works (tm)
-Biasing can be later adjusted per node or per viewport (as well as globally)
-Disabled AABB.get_support test because its broken
-Reworked how meshes are treated by importer by using EditorSceneImporterMesh and EditorSceneImporterMeshNode. Instead of Mesh and MeshInstance, this allows more efficient processing of meshes before they are actually registered in the RenderingServer.
-Integrated MeshOptimizer
-Reworked internals of SurfaceTool to use arrays, making it more performant and easy to run optimizatons on.
We haven't had a proper implementation for COMPRESS_PVRTC2 (which is PVRTC1 2-bpp) in years,
so let's drop it instead of keeping a compress type which doesn't work.
The other enum values were renamed to clarify that our PVRTC2 and PVRTC4 are respectively
PVRTC1 2-bpp and PVRTC1 4-bpp. PVRTC2 2-bpp and 4-bpp are not implemented yet.
-Changed how mesh data is organized, hoping to make it more efficient on Vulkan and GLES.
-Removed compression, it now always uses the most efficient format.
-Added support for custom arrays (up to 8 custom formats)
-Added support for 8 weights in skeleton data.
-Added a simple optional versioning system for imported assets, to reimport if binary is newer
-Fixes #43979 (I needed to test)
WARNING:
-NOT backwards compatible with previous 4.x-devel, will most likely never be, but it will force reimport scenes due to version change.
-NOT backwards compatible with 3.x scenes, this will be eventually re-added.
-Skeletons not working any longer, will fix in next PR.
1. _gen_unique_bone_name(Ref<GLTFState> state, const GLTFSkeletonIndex skel_i, const String &p_name) won't return an empty string.
2. String GLTFDocument::_sanitize_bone_name(const String &name) will keep Japanese characters. Like: "全ての親".
3. The sanitize function allows the bone name to be not just alphanumeric. The only required conditions are the ones in add_bone.
> ERR_FAIL_COND(p_name == "" || p_name.find(":") != -1 || p_name.find("/") != -1);
The glTF 2.0 spec only makes `mimeType` mandatory for `bufferView` image data,
so the previous logic to handle URIs with base64-encoded images could fail if
`mimeType` is undefined.
The logic was documented and refactored to better handle the spec, notably:
- `uri` and `bufferView` are now mutually exclusive, and only the latter fails
if `mimeType` is undefined.
- `uri` with a file path will now respect the `mimeType` if defined, and thus
attempt loading the file with the specified format (even if its extension is
not the one expected for this format). So we can support bad extensions (PNG
data with `.jpg` extension) or custom ones (PNG data in `.img` file for
example).
- `uri` with base64 encoded data will infer MIME type from `data:image/png` or
`data:image/jpeg` if it was not documented in `mimeType` initially.
- `uri` with base64 encoded data, no `mimeType` and `application/octet-stream`
or `application/gltf-buffer` will fall back to trying both PNG and JPEG
loaders.
Fully fixes#33796 (and fixes up #42501).
See https://github.com/KhronosGroup/glTF/issues/944 for context on the
application/gltf-buffer MIME type.
The glTF 2.0 spec supports `image/jpeg` and `image/png` which can also be
base64-encoded in buffer URIs.
Fixes#33796.
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
-o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
-o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```
This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.
This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.
Part of #33027.
