Mipmap LOD bias can be useful to improve the appearance of distant
textures without increasing anisotropic filtering (or in situations
where anisotropic filtering is not effective).
`fsr_mipmap_bias` was renamed to `texture_mipmap_bias` accordingly.
The property hint now allows for greater precision as well.
- Validate format conservatively. (This is to have VRS images created regardless whether VRS attachments are supported, which avoids errors in places where the code assumes such images were created on low-spec GPUs.)
- Create a non-layered default VRS image, which is what Vulkan (and D3D12, by the way) expect.
The new default values are more usable in real world scenarios
when smooth fading of distant decals is desired for performance reasons.
The Decal distance fade property hints were adjusted based on the
GeometryInstance3D visibility range fade property hints. `or_greater`
was also added to allow specifying larger values if needed.
Example with TAA: by default it is `false` in project settings and in
the Viewport node. When the scene tree is created, Viewport.set_use_taa()
is called with the value from ProjectSettings. But because the default
values are already the same, RenderingServer isn't called.
The Viewport struct in the RenderingServer does not initialize this field,
so TAA gets randomly enabled when the game starts with default settings.
Implement built-in classes Vector4, Vector4i and Projection.
* Two versions of Vector4 (float and integer).
* A Projection class, which is a 4x4 matrix specialized in projection types.
These types have been requested for a long time, but given they were very corner case they were not added before.
Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity.
**Q**: Why Projection and not Matrix4?
**A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.
* Moved preprocessor to Shader and ShaderInclude
* Clean up RenderingServer side
* Preprocessor is separate from parser now, but it emits tokens with include location hints.
* Improved ShaderEditor validation code
* Added include file code completion
* Added notification for all files affected by a broken include.
`rendering/quality/shadows` is now `rendering/quality/positional_shadow`
to explicitly denote that the settings only affect positional light shadows,
not directional light shadows.
Shadow atlas settings now contain the word "atlas" for easier searching.
Soft shadow quality settings were renamed to contain the word "filter".
This makes the settings appear when searching for "filter" in the
project settings dialog, like in Godot 3.x.
Spartan Engine has recently removed its own internal TAA in favor
of FSR 2.0. The link has been changed to point to a fixed commit,
so the link will keep working as long as the repository exists.
Antialiased lines with a width of 2 pixels or more now use a smaller
feather width of 1.25 instead of 2.0. This makes them look sharper
and better preserves their original shape while still having good
antialiasing quality.
This also improves the appearance of thin antialiased lines by
slightly increasing their feather size (from 1.0 to 1.25). It
makes them appear a tad thicker, but the antialiasing quality is
much improved by doing this.
* Allows running the game in "movie writer" mode.
* It ensures entirely stable framerate, so your run can be saved stable and with proper sound (which is impossible if your CPU/GPU can't sustain doing this in real-time).
* If disabling vsync, it can save movies faster than the game is run, but if you want to control the interaction it can get difficult.
* Implements a simple, default MJPEG writer.
This new features has two main use cases, which have high demand:
* Saving game videos in high quality and ensuring the frame rate is *completely* stable, always.
* Using Godot as a tool to make movies and animations (which is ideal if you want interaction, or creating them procedurally. No other software is as good for this).
**Note**: This feature **IS NOT** for capturing real-time footage. Use something like OBS, SimpleScreenRecorder or FRAPS to achieve that, as they do a much better job at intercepting the compositor than Godot can probably do using Vulkan or OpenGL natively. If your game runs near real-time when capturing, you can still use this feature but it will play no sound (sound will be saved directly).
Usage:
$ godot --write-movie movie.avi [scene_file.tscn]
Missing:
* Options for configuring video writing via GLOBAL_DEF
* UI Menu for launching with this mode from the editor.
* Add to list of command line options.
* Add a feature tag to override configurations when movie writing (fantastic for saving videos with highest quality settings).
Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934
* Clean up usage of murmur3
* Fixed usages of binary murmur3 on floats (this is invalid)
* Changed DJB2 to use xor (which seems to be better)
- Specular can now be set above 1.0.
- Blur can be set to 0 to disable shadow blurring entirely, which is useful
on lights that have a non-zero size.
- When shadow blurring is disabled, lights that have a non-zero size will
not use PCSS-like soft shadows, speeding up shadow rendering
considerably.
- Some property hints now allow more precise values.
Initial TAA support based on the implementation in Spartan Engine.
Motion vectors are correctly generated for camera and mesh movement, but there is no support for other things like particles or skeleton deformations.
* Replace case-by-case extraction with PNAME & GNAME
* Fix group handling when group hint begins with property name
* Exclude properties that are PROPERTY_USAGE_NO_EDITOR
* Extract missing ADD_ARRAY*, ADD_SUBGROUP* macros
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
Adds a new, cleaned up, HashMap implementation.
* Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing).
* Keeps elements in a double linked list for simpler, ordered, iteration.
* Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much
for performance vs keeping the key, but helps replace old code).
* Uses a more modern C++ iterator API, deprecates the old one.
* Supports custom allocator (in case there is a wish to use a paged one).
This class aims to unify all the associative template usage and replace it by this one:
* Map<> (whereas key order does not matter, which is 99% of cases)
* HashMap<>
* OrderedHashMap<>
* OAHashMap<>

thanks to akien-mga for patiently rewriting my style mistakes
These typedefs don't save much typing compared to the full `Ref<Resource>`
and `Ref<RefCounted>`, yet they sometimes introduce confusion among
new contributors.
This method can be used to get the graphics API version currently in
use (such as Vulkan). It can be used by projects for troubleshooting
or statistical purposes.
`smoothstep()` avoids the sudden transparency jump when entering or
leaving a decal's distance fade margin distance. This in turn helps
make opacity transitions less noticeable to the player, as it's
less likely to catch the player's eye.
Didn't commit all the changes where it wants to initialize a struct
with `{}`. Should be reviewed in a separate PR.
Option `IgnoreArrays` enabled for now to be conservative, can be
disabled to see if it proposes more useful changes.
Also fixed manually a handful of other missing initializations / moved
some from constructors.
Add "generate_mipmap" font import option.
Add some missing features to the Sprite3D.
Move BiDi override code from Control to TextServer.
Add functions to access TextServer font cache textures.
Add MSDF related flags and shader to the standard material.
Change standard material cache to use HashMap instead of Vector.
The default shadow material was used for depth rendering disregarding the cull mode of the original material. This commit adds a check so the default shadow material is only used when the original material has back-face culling.
Fixes a regression introduced by the color pass flags rework. The various rasterizer state structs were not being reset for each flag combination, which meant some state changes were wrongly applied to some flag combinations.
The validation layers were complaining that we use DEFAULT_RD_TEXTURE_WHITE (which is RGBA8) in places where it's sampled as a depth texture. This commit adds the new default texture DEFAULT_RD_TEXTURE_DEPTH and uses it where needed.
This commit removes a lot of enum values related to the color render pass in favor of a new flag-bases approach. This means instead of hard-coding all the possible option combinations into enums, we can write our logic by checking a bit-mask.
The changes in rendering_device_vulkan.cpp add support for unused attachments. That means RenderingDeviceVulkan::framebuffer_create() can take null RIDs in the attachments vector, which will result in VK_ATTACHMENT_UNUSED entries in the render pass.
This is used in this same PR to establish fixed locations for the color pass attachments (only color and separate specular so far, but TAA will add motion vectors as well). This way the attachment locations in the shader can stay the same regardless of which attachments are actually used.
Right now all the combinations of flags are generated, but we will need to add a way to limit the amount of combinations in the future.
* Ability to create script languages from GDExtension
* Some additions to gdnative_extension.h to make this happen
* Moved the GDExtension binder to core
This now allows creating scripting languages from GDExtension, with the same ease as if it was a module. It replaces the old PluginScript from Godot 3.x.
Warning: GodotCPP will need to be updated to support this (it may be a bit of work as ScriptInstance needs to be created over there again).
3 options are available:
- Light and Sky (default)
- Light Only (new)
- Sky Only (equivalent to `use_in_sky_only = true`)

When given roughness is lower than 0.01, d value in original code will
be zero. This can make last return value as NAN because of
divide-by-zero. This is well addressed in issue #56373.

* Changed syntax usage for RD::Uniform to create faster with a single RID
* Converted render pass setup to use this in clustered renderer to test.
This is the first step into creating a proper uniform set cache system to simplify large parts of the codebase.
- Add 2D and 3D in timestamp names when needed to avoid ambiguity.
- Use present tense in all render timestamp names.
- Add a space after ">" (begin) and "<" (end) symbols.
- Remove redundant "End" in render timestamp names (indicated by "<").
This can be used to fade lights and their shadows in the distance,
similar to Decal nodes. This can bring significant performance
improvements, especially for lights with shadows enabled and when
using higher-than-default shadow quality settings.
While lights can be smoothly faded out over distance, shadows are
currently "all or nothing" since per-light shadow color is no longer
customizable in the Vulkan renderer. This may result in noticeable
pop-in when leaving the shadow cutoff distance, but depending on the
scene, it may not always be that noticeable.
* Adds optional vec4 USERDATA1 .. USERDATA6 to particles, allowing to store custom data.
* This data is allocated on demand, so shaders that do not use it do not cost more.
- Enable Read Sky Light to get proper outdoors lighting out of the box.
- Set bounce feedback to 0.5 by default to get a better quality result.
- Higher values may cause infinite feedback with bright surfaces.
- Increase the number of frames to converge to improve quality
at the cost of latency. Most scenes are fairly static after all.
- Use 75% Y scale by default as most scenes are not highly vertical.
- Reorder the Y scale enum to go from the lowest Y scale to the highest.
Also rename the "Disabled" setting to "100%" for clarity.
This improves rendering performance noticeably, especially when the
camera moves fast.
On a medium-sized test scene on a GTX 1080 in 2560×1440, going
from 6 to cascades saves 0.5 ms of frame time while looking visually
identical (as most of the scene fits within the 4 cascades).
16-bit shadow atlases are already the default in the project settings,
but low-level methods used 24-bit shadows by default.
This makes low-level methods more consistent with the default project
settings to avoid accidental performance issues when users change
the shadow size at run-time.
`smoothstep()` avoids the sudden transparency jump when entering or
leaving an object's alpha fade margin distance. This in turn helps
make opacity transitions less noticeable to the player, as it's
less likely to catch the player's eye.
* Erase shadow owner *before* setting it to RID().
* Add default texture in shadow atlas debug view to avoid error spam when no atlas is present.
* Fix typo.
