$opaque
Causes the model to be assumed to be opaque with respect to its sorting against all other objects in the scene. Use this in cases where only a small portion of the model is translucent (hair, eyes, glasses, etc.) so if there are any sorting issues, it won’t matter.

$mostlyopaque
or $opaque
on all models is good form, as it prevents odd lighting errors and visual artifacts with shadows.Syntax
