I am building a displacement/terrain exporter for a game engine. One of the things I am trying to do is use the Projection Modifier for the source of the displacement geometry in the game.

For each vertex in the base geometry (a plane) there is a matching vertex in the projection cage… What I need is to be able to get the location of the vertexes to measure the offsets, etc. I also need to calculate the directions of normals, etc.

The problem is that I am not finding the MAXScript docs very useful here. I’m also not finding anything useful on any of the Google searches.

I just cannot seem to figure out how to reference all the cage nodes, faces, etc. If someone could point me in the right direction, I would greatly appreciate it!

Thanks in advance!

There is an exportCage function which creates a new node from the cage - maybe that would be of some use? Beyond that I don’t know - the documentation is indeed a bit sparse on the subject.
