Road tags impact on performances

Hi MS/Asobo Does the the Road tags in the gltf has the same impact as the
collision ones on CPU performances ? I’d like to know if it is worth putting
this tag only on the more precise Lods (the one that display when the plan it
the model), and not on the other Lods of a model (photogrammetry tile). Also,
i did a simple test: i created collider models with the less precise Lods, and
enabled the Road and collision tag on it, then made those colliders
transparent. It works pretty well for collision detection, but the road
traffic does not display correctly on the model. Is it intended ?
