Hi guys! currently im working on pistol. I dont know what's wrong with the normal map. There is some weird edges on it. Also, where should I harden or soften edges?
Any UV shell splits get a hard edge. Same with any 90 degree or acute angles in the mesh which should be UV mapped to split along those edges anyways. Everything else is soft - sometimes depending on how obtuse the angle of the mesh geo is you can use a soft edge on a UV split, the difference is minimal but can sometimes…
In addition to what DriveJunky95 said. I think you need to read...read...read... Start here....http://polycount.com/discussion/107196/youre-making-me-hard-making-sense-of-hard-edges-uvs-normal-maps-and-vertex-counts#latest
