After Effects error import of 3D-terrain

Not even sure where to push this question. There should be a catch all so newbs like me don’t span the wrong group.

Getting an import error when trying to use 3D-Terrain inside After Effects

Any ideas?

Mac, High Sierra, latest CC

Looks like this is a Photoshop script, not made for After Effects.

If you have further problems contact the author as written in the error message in your last screenshot. (last line)
