Hello, in the programming guide it states:
Module lifetimes need to extend to the lifetimes of ProgramGroups that reference them. Modules may be destroyed after creating the OptixPipeline that uses them through the ProgramGroup objects.
Does the lifetime of the ProgramGroups need to be the same as the OptixPipeline that uses them, or can they safely be destroyed once the pipeline has been created?
Similarly, once a ProgramGroup has been packed into a SBT record header, can it be destroyed? Or must it live as long as the record?
