On the other hand, the image below shows UV Channel 1, which rotates and skews the mapping between the triangles and the UV texture space.

When you use this UV Channel (set by the Coordinate Index property of the TexCoord node), the Material applies the full width and height of a texture to the plane. The Material uses the mapping between 2D coordinates and 3D vertex positions contained in the selected UV Channel to determine which areas of the texture should be used to shade what triangles in the 3D model.įor example, UV Channel 0 in this simple plane Static Mesh (shown at the top right of the following image) shows the simplest way to map the two triangles of the mesh (A and B) into texture space. Texture coordinates in Materials: When you create a Material that samples a texture map and applies it to the surface of a Static Mesh, you can use a Texture Coordinate (or Texcoord) node to specify a UV Channel. UV Channels have two main purposes in the Engine:
However, the Editor does offer a few possibilities for working with the UV Channels of your models, outlined below on this page. You typically create and manage your UV mappings in a dedicated modeling tool-the same tool you use to create the geometry of your Static Mesh. These mappings define how 2D texture maps get wrapped around the 3D geometry when the mesh is rendered.
A UV Channel is a set of data within a Static Mesh that maps each of the mesh's vertices to coordinates in 2D space.
