This reduces visible banding in indirect lighting and reflections.
Sharp reflections now match more closely the original scene.
The downside of this change is that clipping may appear in reflections
in extremely bright scenes, but this should not be a concern in most
scenes.
The message about SpatialMaterial conversion was turned into a warning,
as it can potentially interfere with porting projects from Godot 3.x
(if there's a bug in the conversion code).
In scenes that have little to no overdraw, disabling the depth prepass
can give a small performance boost. Nonetheless, in most other scenarios,
the depth prepass should be left enabled as it improves performance
significantly.
On a GeForce GTX 1080 in 2002×1447 resolution, decreasing VoxelGI quality
from High to Low quality saves 1.2 ms of GPU time in a medium-sized
test scene. This only results in a minor drop in quality.
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
Fixes the SHADOW_CASTING_SETTING_OFF setting in
GeometryInstance3D and the "shadows_disabled" render
mode in spatial materials, which were not working
before.
The built-in ALPHA in spatial shaders comes pre-set with a per-instance
transparency value. Multiply by it if you want to keep it.
The transparency value of any given GeometryInstance3D is affected by:
- Its new "transparency" property.
- Its own visiblity range when the new "visibility_range_fade_mode"
property is set to "Self".
- Its parent visibility range when the parent's fade mode is
set to "Dependencies".
The "Self" mode will fade-out the instance when reaching the visibility
range limits, while the "Dependencies" mode will fade-in its
dependencies.
Per-instance transparency is only implemented in the forward clustered
renderer, support for mobile should be added in the future.
