Introduces a new structure to store samplers created with certain parameters instead of storing a 'custom' set of samplers. Allows viewports to correctly configure the mipmap bias and use it when rendering the scene.
Add the capability of resizing the transforms buffer for particles to be double its size and alternate where the current output is written to. Only works for particles that use index as their draw order.
Extends mesh instances that required custom vertex buffers to create two alternating buffers that are written to and binds them to use them as the previous vertex buffer when generating motion vectors.
Fixes#67287. There was a subtle error where due to how enabling motion vectors for multi-meshes was handled, only the first instance would have a valid transforms buffer and the rest would point to an invalid buffer. This change moves over the responsibility of enabling motion vectors only when changes happen to the individual 3D transforms or the entire buffer itself. It also fixes an unnecessary download of the existing buffer that'd get overwritten by the current cache if it exists. Another fix is handling the case where the buffer was not set, and enabling motion vectors would not cause the buffer to be recreated correctly.
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance
Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.
discard was being included in all shaders set to depth pass opaque, which is the majority of shaders
Instead it should only be used with alpha prepass materials
This allows us to specify a subset of variants to compile at load time and conditionally other variants later.
This works seamlessly with shader caching.
Needed to ensure that users only pay the cost for variants they use
Explicitly clear the separate specular buffer when the background mode is canvas and screen space effects (and thus a separate specular buffer) are used.
This also fixes RENDERING_INFO_TOTAL_PRIMITIVES_IN_FRAME for the RD renderers as it was incorrectly reporting vertex/index count at times
This also adds memory tracking to textures and buffers to catch memory leaks.
This also cleans up some memory leaks that the new system caught.
If using normal buffer debugging or if the normal texture was used, we should use PASS_MODE_DEPTH_NORMAL_ROUGHNESS regardless of whether there is a valid Environment or not. Otherwise, shaders reading the normal texture will not work without a valid Environment (and possibly other problems).
The OpenGL implementation has used GL_FUNC_REVERSE_SUBTRACT for a long time, but the new RenderingDevice abstraction used by the Vulkan renderers had been mistakenly set to BLEND_OP_SUBTRACT instead of BLEND_OP_REVERSE_SUBTRACT.
Fixes#77448
Light3D has a light_specular property which is used to set the
intensity of specular contributed by this light source, but it was
previously only used by the default material light shader, and not
possible to use in a custom light() shader.
Previously, when using doubles builds of the engine, instance transform was stored no matter what which caused world space particles to accumulate the instance transform twice
- Extents are replaced by Size (Size is Extents * 2)
- The UI text displays 'Size'
- Snapping is adjusted to work with Size
- _set and _get handle extents for compatibility

Normally dependencies are only set dirty when changed during culling, but that misses changes that happen in the renderer (like a new shader being set in a material)
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
This argument is now non optional, but this never hits the same bad access.
I voted to simplify the code here since the argument is never used optionally in our codebase.
Previously, only forward basis distance from the camera was used.
This means that unnecessarily high LOD levels were used for objects located to the side of the camera.
The distance from the camera origin is now used, independently of direction.
Negatively scaled objects should be mirrored. This is already implemented, but it breaks when mirrored and non-mirrored instances of the same object are visible together.
It turns out that the code that skips-over repeats in `RenderForwardClustered::_render_list_template` also skips the code that accounts for the culling mode of mirrored objects.
The solution here is to consider the `mirror` flag when determining repeats. This might result in more draw commands than necessary since a mirrored object can split a group of non-mirrored instances in two.
This problem doesn't appear in the mobile renderer because the repeat optimization isn't implemented there yet.
The problem still appears in MultiMeshInstance3D in *all* renderers.
Fixes#62879 and #58546.
