bAllowDuplicateAnyHitShaderInvocation

Any-hit shader may be invoked multiple times for the same primitive during ray traversal.

Windows

MacOS

Linux

Syntax

bool bAllowDuplicateAnyHitShaderInvocation

Remarks

Any-hit shader may be invoked multiple times for the same primitive during ray traversal. Setting this to `false_ guarantees that only a single instance of any-hit shader will run per primitive, at some performance cost.
