Port over the logic from Godot 3.5 for indirect lighting. This should fix many issues about indirect bounces causing more energy and improve the overall quality of the result.
This increases the speed to be near instant and removes the perceived lightmap bake speed regression
We need to investigate the speed and quality issues with BPTC and re-enable compression when we can
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".
- Use 3 bounces by default.
- Enable environment lighting from the scene by default.
- This is not done in `3.x` for compatibility with existing projects,
but it makes sense to do this by default since pretty much all
outdoor scenes benefit from this.
- Set the custom environment color to white (like ReflectionProbe).
- Its default energy is still 0, so it's invisible by default.
- Enable the generation of dynamic object probes by default.
- Tweak the `max_texture_size` property hint for better usability.
- Improve error messages when passing invalid sizes to
`LightmapGI.set_max_texture_size()`.
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.
In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.
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)
The program crashes when trying to determine slice width/height if the
light texture is empty. This fix just returns an empty array, as if the
light texture does not exist.
* Previous "virtual" classes (which can't be instantiated) are not corretly named "abstract".
* Added a new "virtual" category for classes, they can't be instantiated from the editor, but can be inherited from script and extensions.
* Converted a large amount of classes from "abstract" to "virtual" where it makes sense.
Most classes that make sense have been converted. Missing:
* Physics servers
* VideoStream
* Script* classes.
which will go in a separate PR due to the complexity involved.
* Its not and will not be used for streaming.
* Streaming will be implemented in 4.1 and it will work different.
* It makes more sense to be called CompressedTexture since it imports and compresses texture files.
To make baked colors of lights equal to dynamic colors of lights they have to be
converted to linear as the colors of dynamic lights are converted to linear by
RendererSceneRenderRD.
