Hey guys, I have generall question about smoothing groups and normals, from my understanding if i put the same smoothing group on a UV island which is stiched together from 5 different polygons, the result should be "normal issue free" seamless... When stiching the same 5 polygons together to 1 UV Island and i'm using…
The short answer is its because the angle difference between the two polygons is too extreme. Anything you would consider a "corner" (two polygons meeting at 90/270 degree right angles) should definitely have a smoothing split/UV split. If you have a cube on a single smoothing group like above, you're essentially telling…
