I finally have a silly question (that normally I would go and test, but it popped into my mind while away from the PC for once).
I have this new super duper custom palm tree model I just hand carved.
I created the base sculpt with an insane amount of vertices so that I can bake it down into a less expensive version - as usual really, nothing extreme or unusual.
I’m wondering if - assuming I do use the really high poly count model as LOD0 - the LOD1 having a different material ends up costing me an extra draw call at all times, or if the extra drawcall doesn’t even matter because the LOD system already generating a draw call when triggering (which it has to, since it is rendering something essentially “new”).
it would still be just 1 material per mesh/lod (instead of the trees you usually see that have 2 or 3 different materials as a base or for the fronds).
having reached 90fps on a final scene with grass at 4K it probably won’t impact my performance either way, but I am rather curious on if anyone know an answer. If not I’ll end up testing it tomorrow…
