I'm having a problem importing L3DT heightfields into Freeworld3D. After importing a heightfield from L3DT there are holes in the terrain. You can see the terrain here: http://i40.photobucket.com/albums/e216/ ... 3DMesh.jpg.
Even with the holes if you export the terrain and then reimport it into L3DT it looks fine with the correct contours, heights etc. Here is what I did to import the terrain:
1. export from L3DT at 513 x 513 heightfield using the raw format. This is a single tile from a tiled HM. To get the height range to calculate scale I imported this single tile into L3DT.
2. Create a new 512 x 512 terrain in FreeWorld3D.
3. Import the heightfield as raw16. Scale is heightrange/65536. Units per step is the Horizontal Scale in L3DT.
Worked before but not now.
