-Description
-:    This parameter forces Filament to use its default variant for depth passes, such as those used
-     in shadow rendering. This provides an optimization for materials with expensive custom vertex
-     shaders. For example, custom vertex shader computations intended to be consumed by the fragment
-     stage can be skipped during the depth-only pass. This parameter is only meaningful if the
-     material has a vertex block.
-     This parameter should not be set to `true` for vertex blocks that modify geometry (i.e.,
-     modifying `worldPosition`), otherwise shadows may render incorrectly.
