Build environment
Disable depth pre-pass due to log depth.
According to ChatGPT (yes I didn't bother to find sources online again):
"No, the depth pre-pass technique does not work when using a logarithmic depth buffer. The depth pre-pass technique relies on rendering the scene geometry once to populate the depth buffer before performing the actual shading pass. This allows for early depth testing and can help reduce the number of costly fragment shader computations.
However, when using a logarithmic depth buffer, the depth values are transformed non-linearly to improve depth precision in scenes with a large depth range. This non-linear transformation makes the depth values no longer suitable for traditional depth pre-pass techniques, as the ordering of objects in the depth buffer is no longer linear.
Logarithmic depth buffers are generally used to mitigate the issues of depth precision over long distances in scenes, but they come with the trade-off of compatibility with certain rendering techniques that rely on linear depth buffers, such as the depth pre-pass."
Here are the number of rendered vertices (Godot internal monitor) and 3D draw calls.
With depth pre-pass:
Without depth pre-pass:
3.x Logarithmic depth shadow casting
Need help, it is too hard.
Finalize logarithmic depth
Extreme z-far value yields empty far plane due to precision rerror when reconstructing from matrix
Godot version:
3.x and 4.x
OS/device including version:
Mobile and desktop (Android, linux).
Issue description:
When z-far is below 1e6 (which is the cap value on stock Godot 3) everything renders properly.
Otherwise - arbitrary culling occurs because z-far Plane which is returned by normalize() function - is empty.
Steps to reproduce:
Open MRP and navigate the view in editor at different z-far values as on the video:
https://youtu.be/sY_DiETtkl8
Also in-game video:
