The harsher the angle difference is between two smoothed polygons, the more severe the lighting gradient will be on your low poly, as you illustrated in your image. These gradients will be baked into your normal map to compensate for the low poly's vertex normals compared to your high poly's surface normals and can cause visual artifacts after texture compression and mip mapping happen. So if yo..
