How can I apply a texture to a single mesh face?

Question

What is a simple way to apply a texture to a specific face of a mesh?

Answer 1

• In vertex edit mode, mark seams, uv project, add texture, use the uvmap setting.
• Seams are difficult to see. They are necessary to get separation of faces for free movement of the image plane off the uv image editor
• In uv editor only the target face should remain on the image area, all other faces can be moved to the side

• Material Texture .. Image Mapping Extension must be << Clip >>

• In the images below a cube has been modified and the target face is shaped into a trapezoid. The base color is red. Only one face has the texture.
