Hi raytownmike,

re:

Yup, the current code on line 7 in the file _Heightmap.js looks like this:

	var dlm = moi.filesystem.getPathDelimiter();

If you change that to be what I wrote above, like this:

	var dlm = '\\';

Then after that it should work on the Mac. You need to open the file _Heightmap.js in TextEdit.app and edit the 7th line from the top of the file.
