Did you put the loose heightmap.lua file in the global folder and not its whole containing folder.

Oops, my mistake. I put the entire folder "heightmap" with heightmap.lua, readme and licence.
It works now, though it still times out on 32x32.
16x16 works fine.

This looks all very promising!

[edit] On another PC 32x32 also works. 48x48 most of the time. 64x64 times out most of the time.
I have also worked with mesh-based terrain where each pixel of the heightfield represents a 640x640 unit area (i.e. a normal baseplate).

Two problems:

1. There are many many steps to get to the final product, using several different software (some I wrote myself).
2. You can't easily edit the mesh inside MLCad, LDCad, etc. Rendering the mesh happens fast if it is a single object. Rendering is very very slow if you load all the triangles as individual sub-parts. If you want to raise or lower a vertex, you have to manually modify every triangle that meets at that vertex.

Here are some instructions:

Here are some pictures as well as a download link to the terrain files:

This process is not streamlined at all!
