With this PR it's possible to add a collision during the Mesh import, directly in editor.
To generate the shape is possible to chose between the following options:
- Decompose Convex: The Mesh is decomposed in one or many Convex Shapes (Using the VHACD library).
- Simple Convex: Is generated a convex shape that enclose the entire mesh.
- Trimesh: Generate a trimesh shape using the Mesh faces.
- Box: Add a primitive box shape, where you can tweak the `size`, `position`, `rotation`.
- Sphere: Add a primitive sphere shape, where you can tweak the `radius`, `position`, `rotation`.
- Cylinder: Add a primitive cylinder shape, where you can tweak the `height`, `radius`, `position`, `rotation`.
- Capsule: Add a primitive capsule shape, where you can tweak the `height`, `radius`, `position`, `rotation`.
It's also possible to chose the generated body, so you can create:
- Rigid Body
- Static Body
- Area
Infinite inertia:
Not needed anymore, since it's now possible to set one-directional
collision layers in order for characters to ignore rigid bodies, while
rigid bodies still collide with characters.
Ray shapes:
They were introduced as a work around to allow constant speed on slopes,
which is now possible with the new property in CharacterBody instead.
The function `_gen_shape_list` is using the resource `Res<Mesh>`, but during the import phase the resource used is instead `Ref<EditorSceneImporterMesh>`.
Note: the `Ref<EditorSceneImporterMesh>` is an intermediate resource, that will be used to create a `Res<Mesh>` at the end of the import process. `Ref<EditorSceneImporterMesh>` and `Ref<Mesh>` are not inheriting each other, so the internal cast done by `Ref<>` during the assignment, is always null:
```c++
Ref<EditorSceneImporterMesh> import_mesh(/* Assume it's initialized */);
CRASH_NOW(import_mesh.is_null());
Ref<Mesh> mesh = import_mesh;
CRASH_NOW(mesh.is_null()); // <--- Here we have a crash, since it's impossible perform the above cast, and the `mesh` is always null.
```
Here the full list of call to `_gen_shape_list`, where we can notice that a `Ref<EditorSceneImporterMesh>` is passed:
- https://github.com/AndreaCatania/godot/blob/master/editor/import/resource_importer_scene.cpp#L428
- https://github.com/AndreaCatania/godot/blob/master/editor/import/resource_importer_scene.cpp#L454-L458
- https://github.com/AndreaCatania/godot/blob/master/editor/import/resource_importer_scene.cpp#L512-L516
As you can notice, we always pass the following mesh: `Ref<EditorSceneImporterMesh> mesh = mi->get_mesh();`.
We already have the function `_pre_gen_shape_list` that executes the exact same job but using the correct type; Since there is no further usage of the function `_gen_shape_list` in the code base, I think it's just some leftover code, so I removed it entirely to use the proper function.
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.
This is part of ongoing work to optimize GUI and the editor.
Clean: remove duplicate and interior vertices (uses Bullet algorithm)
Simplify: modify the geometry for further simplification (uses VHACD
algorithm)
In the editor, single convex hull now uses the clean option.
Added a new editor entry to create a simplified convex hull, can be
useful for creating convex hull from highly tessellated triangle meshes.
* Functions to convert to/from degrees are all gone. Conversion is done by the editor.
* Use PROPERTY_HINT_ANGLE instead of PROPERTY_HINT_RANGE to edit radian angles in degrees.
* Added possibility to add suffixes to range properties, use "min,max[,step][,suffix:<something>]" example "0,100,1,suffix:m"
* In general, can add suffixes for EditorSpinSlider
Not covered by this PR, will have to be addressed by future ones:
* Ability to switch radians/degrees in the inspector for angle properties (if actually wanted).
* Animations previously made will most likely break, need to add a way to make old ones compatible.
* Only added a "px" suffix to 2D position and a "m" one to 3D position, someone needs to go through the rest of the engine and add all remaining suffixes.
* Likely also need to track down usage of EditorSpinSlider outside properties to add suffixes to it too.
Renames get_parent_spatial() to get_parent_node3d() and changes its
implementation. Before it was not returning a correct pointer if the
node wasn't added to a SceneTree. Now it uses the same implementation as
CanvasItem, which will be correct even for nodes outside a SceneTree.
This can be used to invert a normal map's direction.
The "Invert" import option is no longer useful in Godot 4.0 since
it uses height maps instead of depth maps in StandardMaterial3D.
This closes https://github.com/godotengine/godot-proposals/issues/785.
This changes the types of a big number of variables.
General rules:
- Using `uint64_t` in general. We also considered `int64_t` but eventually
settled on keeping it unsigned, which is also closer to what one would expect
with `size_t`/`off_t`.
- We only keep `int64_t` for `seek_end` (takes a negative offset from the end)
and for the `Variant` bindings, since `Variant::INT` is `int64_t`. This means
we only need to guard against passing negative values in `core_bind.cpp`.
- Using `uint32_t` integers for concepts not needing such a huge range, like
pages, blocks, etc.
In addition:
- Improve usage of integer types in some related places; namely, `DirAccess`,
core binds.
Note:
- On Windows, `_ftelli64` reports invalid values when using 32-bit MinGW with
version < 8.0. This was an upstream bug fixed in 8.0. It breaks support for
big files on 32-bit Windows builds made with that toolchain. We might add a
workaround.
Fixes#44363.

Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for
context in case of git blame/bisect:
* Fix UV2 unwrapping on import, also cleaned up the unwrap cache code.
* Fix saving of RGBA images in EXR format.
* Fixes to the GPU lightmapper:
- Added padding between atlas elements, avoids bleeding.
- Remove old SDF generation code.
- Fix baked attenuation for Omni/Spot lights.
- Fix baking of material properties onto UV2 (wireframe was
wrongly used before).
- Disable statically baked lights for objects that have a
lightmap texture to avoid applying the same light twice.
- Fix lightmap pairing in RendererSceneCull.
- Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`.
- Port autoexposure fix for OIDN from 3.x.
- Save debug textures as EXR when using floating point format.
- For now everything imports multithreaded by default (should work I guess, let's test).
- Controllable per importer
Early test benchmark. 64 large textures (importing as lossless, _not_ as vram) on a mobile i7, 12 threads:
Importing goes down from 46 to 7 seconds.
For VRAM I will change the logic to use a compressing thread in a subsequent PR, as well as implementing Betsy.
