priority
Provides coarse-grained control over draw order.
The priority is applied separately for opaque and translucent objects, that is, opaque objects are always drawn before translucent objects regardless of the priority. Priority is orthogonal to layerMask, which merely controls visibility.
Return
Builder reference for chaining calls.
Parameters
