I love 3DE its so powerful, the UI is quirky but thats allright.
I usually dont use the mesh extraction tools and just make some geometry in meshroom, clean it up in blender and then ust this as survey. And yes vfx tutor tutorials are crazy good on this.
Tbh for a quick cameratrack with geometry… meshroom is basically one click and done but its not made to work with lensdistortion etc so its a bit “simple”
what also works well is nukes pointcloud generator, then you at least have a pointcloud to match stuff to.
But yea start with a mesh first then track it that seems to be the best way for gettig stuff bery accurately hence on set lidar scanning and or photogrammetry.
