[Error] CS1061: ‘PostProcessRenderContext’ does not contain a definition for ‘stereoRenderingMode’
You are using an old version of the Post Processing Stack, update to the latest version through the Package Manager. A minimum of v2.0.17 is required.
[Error] failed to open source file: ‘../../../Shaders/StdLib.hlsl’ at line X
This shouldn’t happen in any case, ensure that all the files in the “Shaders” folder were imported.
This can also be a false positive. In which case you can click on the error, which will highlight the shader file. Next right-click on the shader and choose “Reimport”, this will nudge things back into place. This started happening since Unity 2019.1 and is likely a bug in the revised shader compiler…
[Error] RenderingCommandBuffer: invalid pass index X in DrawMesh
This error is thrown if there is a shader error, or a shader is missing. Be sure to have all package contents imported and use the latest Post Processing Stack version.
Fog is gray when color mode is set to Skybox
If you’re using the LWRP in Uity 2019.1.2 or newer, unfortunately this feature is broken. Due to yet another API change in the render pipeline. I currently know of no way to circumvent this.
This may also happen in scene view, in which case a Unity restart will fix this, or closing the scene view tab and reopening it (CTRL+1).
Fog noise or Cloud Shadows start twitching when looking directly towards the Z-axis
This is a very specific and odd occurrence related to using Temporal Anti-Aliasing with these effects.
When the camera is perpendicular to a XYZ axis, the sketch projection will appear to morph slightly.
The Fog effect may show artifacts where the skybox and objects meet.
Disable (MSAA) Anti Aliasing in your Quality Settings
When using Metal rendering on macOS, you may see the following warning: “Metal: Fragment shader missing texture binding at index X”.
Disable “Metal API Validation” in your Player Settings to resolve this. This warning will be thrown when a shader has an empty texture assigned, but is harmless.
