There was an issue caused by Antialiasing being done after DoF. Move TAA
after DOF and Motion Blur.
Also certain pixel with lower CoC would be spread all over the background
because the neighbooring pixel have higher CoC. So we need to apply some
bilateral filtering when downsampling. Currently we limit the influence of
neighbor pixels with a CoC inside the range [MaxCoC-2, MaxCoC].
Note to myself, next time, better check the fix before pushing it.
GL_ARB_texture_gather is defined if there is support for the extension
not only when the extension is enabled. Do this check ourself with
GPU_ARB_texture_gather define.
Original fix 822de6e9e1
The extension GL_ARB_texture_gather is reported to be supported and does
not trigger an error when enabled but the textureGater functions are not
defined.
Workaround is to disable the use of this extension on such systems.
This is more like a static optimisation when some parameters are set to 1.0
or 0.0. In theses case we use a more optimized version of the node.
This also revisit the transmission parameter behaviour to make it closer to
cycles.
Some of them are unecessary and should be removed from the shader instead.
But for now we need a quick fix for the crashes happening on some platforms.
See T55475.
This ignores the scene color managment view settings for solid mode and
lookdev when not using scene lights and world. The scene settings are
intended for tweaking renders and should not affect studio lighting and
matcaps.
There may be cases where a simple sRGB transform is better than Filmic
and we could add configuration for this. Not sure if it really matters
and it may be better if we just assume matcaps and studiolights are all
created for one view transform.

This does not include all the struct and type renaming. Only files were
renamed.
gwn_batch.c/h was fusioned with GPU_batch.c/h
gwn_immediate.c/h was fusioned with GPU_immediate.c/h
gwn_imm_util.c/h was fusioned with GPU_immediate_util.c/h
This separate probe rendering from viewport rendering, making possible to
run the baking in another thread (non blocking and faster).
The baked lighting is saved in the blend file. Nothing needs to be
recomputed on load.
There is a few missing bits / bugs:
- Cache cannot be saved to disk as a separate file, it is saved in the DNA
for now making file larger and memory usage higher.
- Auto update only cubemaps does update the grids (bug).
- Probes cannot be updated individually (considered as dynamic).
- Light Cache cannot be (re)generated during render.
- Change gl_context_mutex to a ticket mutex ensuring interactivity even
when rendering.
- Add DRW_custom_pipeline for using DRW outside of the viewport and render
pipeline.
- DRW_opengl_render_context_*** and DRW_gawain_render_context_*** to use
with DRW_custom_pipeline.
- Add possibility to bypass deferred compilation on demand (not User
demand).
- Add union to access DRWMatrixState members more easily.
Now we light with just a user defined HDRI by default, which is useful
for material setup and texture painting and lighting without having to
set up any scene lights.
Previously it would use the scene world without lights by default, which
in some files is just black.
