Importing DEM and Geotiff data in to Torque 3D

Is there a way to import USGS 10 Meter DEM data into Torque 3D?
Can I use Geotiff as the texture?

Thanks,

I think the only way to get DEM data in is to convert it to a greyscale heightmap, so GeoTiff as a texture would be a no-no.

I use MicroDem with the GoogleEarth SRTM plugin.

What I am looking at doing is using DEM data to make a heightmap. I can do this with MicroDem.

What I want to use the imagery from the assoicated GeoTiff. I want to pull out the imagery from the GeoTiff and drape it as a texture over the heightmap.

Has anyone done this??

Not really possible, not unless you swap the terrain heightmap for a mesh object with visible collision, and sort out the associated UV in a 3D modeling app.

An alternative could be to work out various "layers" of terrain type from the geotiff, and then create opacity layers for them. See the docs on World Editor -> Create Terrain for some info on that.
