They totally are!! But sometimes (it's very very rare) it actually ends up being worth it. I've done some test renders (which are terrible of course) in terragen of the terrain model and they are absolutely incredible when it comes to the amount of detail available. I've been dying to get ahold of a better terrain model of Mt. St. Helens for so long (I started in Vue 3 with the 30 meter res, went to 10 meters with Vue 4 and now...3 meter res data right there!!!), it's really frustrating to have it right freaking there and not be able to get it into the program I can actually make decent renders in because somebody somewhere decided that "it would just be too easy to simply put plain ordinary links to the data, we should bury it so deep that they'll have to spend months just to get to it."
