This also makes the Overdraw and Shadow Splits debug draw modes ignore fog.
The Lighting debug draw mode still displays fog as that debug draw mode
is intended to preview scene lighting, and fog has an impact on how
lighting is perceived.
Adds a new system to automatically reorder commands, perform layout transitions and insert synchronization barriers based on the commands issued to RenderingDevice.
This fixes a bugs where per-viewport samplers were being used for internal texture fetches (probes, sky, etc.).
This also fixes a bug when using multiple viewports in the same scene.
This also fixes a bug where the texture bias would override the bias from 3D scale.
Ensure `ensure_tangents` option actually creates tangent array. Even if it is just a dummy array.
Allow mesh to generate its own tangents when using compression. This allows users to compress meshes without tangents.
Warn users if they are trying to read from tangents without providing tangents.
This is a longstanding issue in both the Mobile and GL Compatibility renderer.
Meshes pair with all lights that touch them, and then at draw time, we send all paired lights indices to the shader (even if that light isn't visible). The problem is that non-visible lights aren't uploaded to the GPU and don't have an index. So we end up using a bogus index
This allows Godot to automatically compress meshes to save a lot of bandwidth.
In general, this requires no interaction from the user and should result in
no noticable quality loss.
This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.
Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.
Introduces support for FSR2 as a new upscaler option available from the project settings. Also introduces an specific render list for surfaces that require motion and the ability to derive motion vectors from depth buffer and camera motion.
Introduces a new structure to store samplers created with certain parameters instead of storing a 'custom' set of samplers. Allows viewports to correctly configure the mipmap bias and use it when rendering the scene.
Add the capability of resizing the transforms buffer for particles to be double its size and alternate where the current output is written to. Only works for particles that use index as their draw order.
Extends mesh instances that required custom vertex buffers to create two alternating buffers that are written to and binds them to use them as the previous vertex buffer when generating motion vectors.
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance
Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.
discard was being included in all shaders set to depth pass opaque, which is the majority of shaders
Instead it should only be used with alpha prepass materials
