Is it possible to place more than one image_map into a height_field. I 
have two tga images I would like to overlay onto a height_field created 
from a DEM (imported into POVRay as a tga image).

The two images make up different parts of the overall image, i.e., land 
and water. Each image_map is brought in as a pigment object.

I have tried applying to pigments (image_maps) to the same height_field, 
but POVRay only draws the second pigment. I have also tried using 
texture layers to do this. That didn't work as well.

Does anybody have any clues that might help?

Thanks?
