Applying Textures

There are a couple of ways to texture your ModelBuilder models in Nuke:

If your 3D model closely matches the original 2D footage, you can project the 2D footage onto the geometry. See Projecting Textures onto Your Shapes.

Projecting the original 2D footage onto the geometry.

If you have added new objects over the top of your 2D footage (for example, added a new window to a building or extra bins alongside a street), you can't project your 2D footage over those objects because they were never in the original footage. Instead, you need to supply a texture from somewhere else and map it over the surface of your 3D object. See UV Unwrapping.

Texturing an added cube object separately.
