When the film is set to transparent the environment pass should still be
rendered solid. otherwise it renders black.

This avoid having a much higher memory footprint as the underlying texture
size allocated by the driver is likely to be much higher (rounded to next
Power of 2 or other alignement requirements).

This follows Cycles closer.

In the viewport an object can be set to be displayed as wire. When
rendering the viewport this setting is ignored and follows the
path or doing a final render. This patch will add an exception
when rendering a viewport render.

Just a matter of not clearing the updating flag in this case.
|
|
This was caused by a missing DRWPass initialization.
Now we create the passes for every timestep but avoid clearing the
buffer after the first sample.
|
|
|
|
|
|
This was caused by the step motion blur implementation.
`DRW_cache_restart` was reseting the cache and cause
`EEVEE_renderpasses_postprocess` to not work inside
`EEVEE_render_read_result`.
|
|
We now bypass EEVEE's rendering if the TAA accumulation has ended.
|
|
This revisit the render pipeline to support time slicing for better motion
blur.
We support accumulation with or without the Post-process motion blur.
If using the post-process, we reuse last step next motion data to avoid
another scene reevaluation.
This also adds support for hair motion blur which is handled in a similar
way as mesh motion blur.
The total number of samples is distributed evenly accross all timesteps to
avoid sampling weighting issues. For this reason, the sample count is
(internally) rounded up to the next multiple of the step count.
Only FX Motion BLur: {F8632258}
FX Motion Blur + 4 time steps: {F8632260}
FX Motion Blur + 32 time steps: {F8632261}

This adds object motion blur vectors for EEVEE as well as better noise
reduction for it.
For TAA reprojection we just compute the motion vector on the fly based on
camera motion and depth buffer. This makes possible to store another motion
vector only for the blurring which is not useful for TAA history fetching.
Motion Data is saved per object & per geometry if using deformation blur.
We support deformation motion blur by saving previous VBO and modifying the
actual GPUBatch for the geometry to include theses VBOs.
We store Previous and Next frame motion in the same motion vector buffer
(RG for prev and BA for next). This makes non linear motion blur (like
rotating objects) less prone to outward/inward blur.
We also improve the motion blur post process to expand outside the objects
border. We use a tile base approach and the max size of the blur is set via
a new render setting.
We use a background reconstruction method that needs another setting
(Background Separation).
Sampling is done using a fixed 8 dithered samples per direction. The final
render samples will clear the noise like other stochastic effects.
One caveat is that hair particles are not yet supported. Support will
come in another patch.

These are the modifications:
-With DRW modification we reduce the number of passes we need to populate.
-Rename passes for consistent naming.
-Reduce complexity in code compilation
-Cleanup how renderpass accumulation passes are setup, using pass instances.
-Make sculpt mode compatible with shadows
-Make hair passes compatible with SSS
-Error shader and lookdev materials now use standalone materials.
-Support default shader (world and material) using a default nodetree internally.
-Change BLEND_CLIP to be emulated by gpu nodetree. Making less shader variations.
-Use BLI_memblock for cache memory allocation.
-Renderpasses are handled by switching a UBO ref bind.
One major hack in this patch is the use of modified pointer as ghash keys.
This rely on the assumption that the keys will never overlap because the
number of options per key will never be bigger than the pointed struct.
The use of one single nodetree to support default material is also a bit hacky
since it won't support concurent usage of this nodetree.
(see EEVEE_shader_default_surface_nodetree)
Another change is that objects with shader errors now appear solid magenta instead
of shaded magenta. This is only because of code reuse purpose but could be changed
if really needed.

This makes it easier to track as well as allowing us to sample the same
texture with different sampling parameters (which should fix the related
T73942 in the long run).

When sculpting the GPU batches are constructed with only the required data
for a single viewport. When that viewport changes shading or coloring mode (object
to vertex) batches might not hold all the needed information.
There is also a case when you have two 3d viewport one in object color
mode and the other in vertex color mode that the GPU batches were
updated without any vertex colors.
In order to fix these category of issues this patch would always
construct the full GPU batches for sculpting.

This fix the issue by introducing a default material only for collection
holdouts. This avoids hash colision when the same material is used in
collections without holdout enabled.
|
|
|
|
The material indices in a mesh can exceed the number of available materials
slots in the object or mesh, sculpt drawing was not taking that into account.

EEVEE and Workbench both had the same issue that they continue with the
last sample when leaving navigating. This is ok for regular meshes as
they are all the same. For multiresolution it ain't as a low res version
of the mesh is used during navigation.
This patch also resets the AA samples when the user leaves navigation.

This does not change the ouput much.

Problem is that the RenderEngines will change the RenderData cfra when
rendering (when time remapping is used -- at least workbench/eevee/
gpencil do a combination of BKE_scene_frame_get() plus
RE_GetCameraWindow() which alters the RenderData cfra).
Later on in the pipeline, the Compositor will use this RenderData cfra
to determine the output file name for the FileOutput node. (In contrast
to this, the 'regular' Output will use the Scene's RenderData -- not the
Render's -- cfra [which hasnt been altered])
It is not entirely clear why RE_GetCameraWindow was setting the cfra on
the Render, but it appears to be legacy OGL rendering related and is not
needed anymore.
Removing this will keep the cfra as needed for the Compositor FileOutput
node.

Also rename START to BEGIN (matching BEGIN/END for most iterator macros).

{F7588610}
And no alpha hashing:
{F7588615}
Note that this needs "soft shadows" enabled, otherwise shadows will be noisy; here's a render with soft shadows disabled:

* Step Size: override automatic step size
* Clipping: values below this are ignored for tighter volume bounds
The last two are Cycles only currently.

Only the volume drawing part is really finished and exposed to the user. Hair
plugs into the existing hair rendering code and is fairly straightforward. The
pointcloud drawing is a hack using overlays rather than Eevee and workbench.
The most tricky part for volume rendering is the case where each volume grid
has a different transform, which requires an additional matrix in the shader
and non-trivial logic in Eevee volume drawing. In the common case were all the
transforms match we don't use the additional per-grid matrix in the shader.
