  • Lightmap UVs Overlapping - UE4 AnswerHub

    Can someone give me a fool proof method so that when I import meshes, im not met with a overlapping UV message after building lighting and black textures. I know it has something to do with rebuilding UVs but im a noob and dont understand. some of the meshes are purchased online and they always end up having the same type of problem.

  • UV mapping - Wikipedia

    UV mapping is the 3D modeling process of projecting a 2D image to a 3D model's surface for texture mapping.The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common operation in computer graphics

    Mar 09, 2016· The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.

  • Overlapping UVs - Normal Problem

    Oct 07, 2015· The UVs should be offset, though. For example: Your UVs are laid out in the 0-1 UV space. Your overlapping UVs (duplicates) should be placed in the 1-2 space, mostly in the quadrant right next to the default one. It's still quite difficult to 'overlap' normal map UVs this way, because it could lead to normal errors in some renderers. Best Regards.
