public string[] optionalDoubleSidedShaderKeywords;

Description

An array of Shader Keywords for defining double-sided geometries.

If a Shader Keyword from the list is enabled at the time when RayTracingAccelerationStructure.CullInstances is called, then the geometry that uses that Shader will be considered double-sided when rays encounter the geometry during acceleration structure traversal on the GPU.
