Best to leave all this at the default settings unless you really know what you are doing. (i.e. check out the python script and see how all this is referenced)

When you select camera use it tells the python script to use the 3D camera space and I’m pretty sure I haven’t tackled that yet.

Currently the camera is setup as an orthographic project which works for most of my needs. In order to use a perspective camera you will need to address the issue above. I recall Matthew Braun having a library that would help with the conversion from worldspace to cameraspace.
