3D models are UV unwrapped into two dimensions in order for textures to be applied to them. At the seams where these models are unwrapped, there will also be seams in the texture that are plainly visible in-game. There is, however, a way to mask these seams by creating a blended transition between the two surrounding textures. This tutorial will show how to do this using decals. | 3D models are UV unwrapped into two dimensions in order for textures to be applied to them.

− | + | One your mesh is UV unwrapped and textured, select the faces comprising the area where a blended transition should happen. Often this will be a "skirt", i.e. a strip of faces running along the seam. The skirt mesh might cover only one of the materials on one side of the seam, or it can cover the seam and thus parts of both materials. In other cases where one of the textures is only on a small amount of geometry (like the end cap of a wooden beam), the blending zone may cover all of this texture's faces. | |
Duplicate these faces (shift+D in blender) and break into a new mesh (P, selection). If the mesh covers only one of the materials (either as a skirt mesh or as fully duplicated geometry), UV it so it is a continuation of the ''other'' material. If it's a skirt mesh that overlaps both materials, then the UV doesn't matter. | Duplicate these faces (shift+D in blender) and break into a new mesh (P, selection).
