There are two texture mapping modes in Lumion: You can either use the imported texture coordinates or Lumion's automatic texture mapping system.
The way you switch between these modes is via the Scale slider in the Standard material. Scale = 0 means that the imported texture coordinates are used. Scale > 0 means that the automatic texture mapping system is used (This is explained when you open a Standard material, and place the mouse cursor above the blue question mark button in the lower right corner).
To place textures in Lumion using the automatic texture mapping system, set the Scale slider to the desired value, then adjust Placing -> Heading/Pitch/Bank/X/Y/Z sliders.
Just bear in mind that the automatic texture mapping system does not work well in all situations, especially on organic shapes.
