+If true, enables parts of the shader required for GPUParticles3D trails to function.
+This also requires using a mesh with appropriate skinning, such as RibbonTrailMesh
+or TubeTrailMesh. Enabling this feature outside of materials used in GPUParticles3D
+meshes will break material rendering.

+Use Z Clip Scale
+~~~~~~~~~~~~~~~~
+
+Scales the object being rendered towards the camera to avoid clipping into things
+like walls. This is intended to be used for objects that are fixed with respect to
+the camera like player arms, tools, etc. Lighting and shadows will continue to work
+correctly when this setting is adjusted, but screen-space effects like SSAO and SSR
+may break with lower scales. Therefore, try to keep this setting as close to 1.0 as
+possible.
+
+Use FOV Override
+~~~~~~~~~~~~~~~~
+
+Overrides the ``Camera3D``'s field of view angle (in degrees).
+
+.. note::
+  This behaves as if the field of view is set on a ``Camera3D`` with
+  ``Camera3D.keep_aspect`` set to ``Camera3D.KEEP_HEIGHT``. Additionally, it may not
+  look correct on a non-perspective camera where the field of view setting is
+  ignored.
