^ Post your UVs, baked normal map, and smoothing. If you're still having similar artifacts as above after those mentioned changes, I've a feeling your normal map has gradients that can be resolved with better hard edge/smoothing placement.
And, i am here again :) Carefull - long post here. Did a lot of research. Searched all possible options via google - seems like no one models mid-poly cars these days :D What i am trying to achieve: nice smoothed mid poly car model with proper reflectons and without normal map on its body. Stuff that we can see in every…
As I remember we've discussed these kinds of smoothing errors backwards and forwards before, but I can't remember if there was ever any resolution besides adding more detail to the low poly or using smoothing groups (blech).
