I made a simple script to export camera animation, including position, rotation and focal length from Lightwave to Terragen. The script exports a camera node and a render node to be imported into Terragen in order to perfectly match camera between them.
The script also exports a .chan file that can be used to match Lightwave camera with Nuke camera.
This script is download free: https://artstn.co/m/z2Vlq
