Description

This structure is used by RayTracingAccelerationStructure.CullInstances function to determine triangle culling and vertex winding order for ray tracing instances.

Additional resources: RayTracingAccelerationStructure.

Properties

checkDoubleSidedGIMaterialWhether to check Material.doubleSidedGI property for determine if a ray tracing instance is considered having double sided geometry.
forceDoubleSidedDisables triangle culling when rays encounter geometries during acceleration structure traversal on the GPU. All other options that affect triangle culling are ignored.
frontTriangleCounterClockwiseThis property reverses front and back facings triangles, which is useful if for example, the application’s natural winding order differs from the default.
optionalDoubleSidedShaderKeywordsAn array of Shader Keywords for defining double-sided geometries.
