Parameters

Name	Description
instance	The instance to add to the TLAS.
blas	The bottom-level acceleration structure that contains the geometries of the instance.
id	The instance ID used in shaders to identify the instance.
hitGroupOffset	An offset added to the shader-local data for a hit-group shader record.
mask	A user defined mask value that can be used to include or exclude the instance during a ray-tracing pass.
flags	The flags that control the behavior of the instance.
transform	The transformation matrix applied to the instance geometry.
