Hey all,
I'm not sure if this is the right place for new tutorials, I checked the wiki page, but it is still marked as Terragen 2/3 and doesn't seem to have been updated for quite a while.
Anyways, here's a video I put together showing my workflow for simulating drone mapping flights in Terragen. The Terragen side of things is relatively simple, but it walks through bringing in public elevation data and satellite imagery, placing object populations, importing flight paths and camera poses from Mission Planner, and creating a 3D model from the resulting imagery. It's been useful for some of our beginners, and I thought it might be of interest.
