InstancedOffset

Either a BVH node or a meshlet, along with the instance it is associated with. Refers to BVH nodes in meshlet_bvh_cull_queue and meshlet_second_pass_bvh_queue, where offset is the index into meshlet_bvh_nodes. Refers to meshlets in meshlet_meshlet_cull_queue and meshlet_raster_clusters. In meshlet_meshlet_cull_queue, offset is the index into meshlet_cull_data. In meshlet_raster_clusters, offset is the index into meshlets.
