Update copyright statements to 2021 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 🎆 (cherry picked from commit b5334d14f7a471f94bcbd64d5bae2ad853d0b7f1)

#ifndef BAKED_INDIRECT_LIGHT_H
#define BAKED_INDIRECT_LIGHT_H
Implement new CPU lightmapper Completely re-write the lightmap generation code: - Follow the general lightmapper code structure from 4.0. - Use proper path tracing to compute the global illumination. - Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper) - Use OpenImageDenoiser to improve the generated lightmaps. - Take into account alpha transparency in material textures. - Allow baking environment lighting. - Add bicubic lightmap filtering. There is some minor compatibility breakage in some properties and methods in BakedLightmap, but lightmaps generated in previous engine versions should work fine out of the box. The scene importer has been changed to generate `.unwrap_cache` files next to the imported scene files. These files *SHOULD* be added to any version control system as they guarantee there won't be differences when re-importing the scene from other OSes or engine versions. This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress; Was then finished and polished by me on my free time. Co-authored-by: Pedro J.

Batch of lightmapper fixes and minor improvements - Fix objects with no material being considered as fully transparent by the lightmapper. - Added "environment_min_light" property: gives artistic control over the shadow color. - Fixed "Custom Color" environment mode, it was ignored before. - Added "interior" property to BakedLightmapData: controls whether dynamic capture objects receive environment light or not. - Automatically update dynamic capture objects when the capture data changes (also works for "energy" which used to require object movement to trigger the update). - Added "use_in_baked_light" property to GridMap: controls whether the GridMap will be included in BakedLightmap bakes. - Set "flush zero" and "denormal zero" mode for SSE2 instructions in the Embree raycaster. According to Embree docs it should give a performance improvement.

Add a property to control the bounce indirect energy in BakedLightmap Higher values will make indirect lighting brighter. A value of 1.0 represents physically accurate behavior, but higher values can be used to make indirect lighting propagate more visibly when using a low number of bounces. This can be used to speed up bake times by lowering the number of bounces then increasing the bounce indirect energy. Unlike BakedLightmapData's energy property, this property does not affect direct lighting emitted by light nodes or emissive materials.

Implement new CPU lightmapper Completely re-write the lightmap generation code: - Follow the general lightmapper code structure from 4.0. - Use proper path tracing to compute the global illumination. - Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper) - Use OpenImageDenoiser to improve the generated lightmaps. - Take into account alpha transparency in material textures. - Allow baking environment lighting. - Add bicubic lightmap filtering. There is some minor compatibility breakage in some properties and methods in BakedLightmap, but lightmaps generated in previous engine versions should work fine out of the box. The scene importer has been changed to generate `.unwrap_cache` files next to the imported scene files. These files *SHOULD* be added to any version control system as they guarantee there won't be differences when re-importing the scene from other OSes or engine versions. This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress; Was then finished and polished by me on my free time. Co-authored-by: Pedro J.

bool use_denoiser;
Add options to reduce lightmaps disk usage. Added BakedLightmap.use_hdr and BakedLightmap.use_color properties that can reduce the flie size of lightmap texture at the expense of quality. Changed the denoiser to work in a single buffer, reducing RAM usage. Also added the `-mstackrealign` flag in the denoiser compilation for MinGW builds. This flag helped fix a bug in Embree, so I want to see if it will help fix GH #45296.

Batch of lightmapper fixes and minor improvements - Fix objects with no material being considered as fully transparent by the lightmapper. - Added "environment_min_light" property: gives artistic control over the shadow color. - Fixed "Custom Color" environment mode, it was ignored before. - Added "interior" property to BakedLightmapData: controls whether dynamic capture objects receive environment light or not. - Automatically update dynamic capture objects when the capture data changes (also works for "energy" which used to require object movement to trigger the update). - Added "use_in_baked_light" property to GridMap: controls whether the GridMap will be included in BakedLightmap bakes. - Set "flush zero" and "denormal zero" mode for SSE2 instructions in the Embree raycaster. According to Embree docs it should give a performance improvement.

int get_bounces() const;
Add a property to control the bounce indirect energy in BakedLightmap Higher values will make indirect lighting brighter. A value of 1.0 represents physically accurate behavior, but higher values can be used to make indirect lighting propagate more visibly when using a low number of bounces. This can be used to speed up bake times by lowering the number of bounces then increasing the bounce indirect energy. Unlike BakedLightmapData's energy property, this property does not affect direct lighting emitted by light nodes or emissive materials.

Implement new CPU lightmapper Completely re-write the lightmap generation code: - Follow the general lightmapper code structure from 4.0. - Use proper path tracing to compute the global illumination. - Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper) - Use OpenImageDenoiser to improve the generated lightmaps. - Take into account alpha transparency in material textures. - Allow baking environment lighting. - Add bicubic lightmap filtering. There is some minor compatibility breakage in some properties and methods in BakedLightmap, but lightmaps generated in previous engine versions should work fine out of the box. The scene importer has been changed to generate `.unwrap_cache` files next to the imported scene files. These files *SHOULD* be added to any version control system as they guarantee there won't be differences when re-importing the scene from other OSes or engine versions. This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress; Was then finished and polished by me on my free time. Co-authored-by: Pedro J.

-Add lightmapper -Fixes to unwrapper (remove degenerates), makes Thekla not crash -Added optional cancel button in EditorProgress -Added function to force processing of events (needed for cancel button)
