I would guess ASCII raw data file. It's possible TG could load it. Did you try the Geog Heightfield Load?

Yeah I did a multiple Heightfield load and TG took it but so far no displacement happened... :D

Turn off Georeferencing... Also, try it with a single heightfield first. Multiple is for loading adjacent tiles and just complicates things.

Well I got no options like that. I looked like 10x by now and cant see it.
I load this file as Heightfield DEM. Then I get a Heightfield shader and a loader but none of this have any option u mentioning.
At least I can't see it... ???

In that case it shouldn't be georeferencing anyway, and you should see the displacement from the terrain at the 0,0 coordinate origin. Check the heightfield size. It may be really small? You could use a Heightfield Resize on it in that case...
