Is Settings -> Enable Low memory compatibility turned on by any chance?
If not, simply apply a Standard material to the mountain range model, and load the texture manually.
Low mem mode on: Textures that are bigger than 1024x1024 pixels are automatically reduced to 512x512 pixels. There is no override function.
Low mem mode off: If you import a model that uses over 100mb of texture memory, Lumion will cap the maximum texture resolution at 2048x2048 pixels. However, you can bypass this limit by pressing CTRL while you click on the Reload model button. If you apply a Standard or Lightmap material to your imported model, any texture you load will be loaded at whatever resolution your graphics card is capable of displaying (up to a maximum of 16384x16384 pixels).
