We are currently just processing our models in 2.5D (no overhangs and verticals aren't textured) for creating orthomaps. Creating a full 3D model takes 4 times as much processing. We will be offering full 3D processing soon but it will require a 4X multiplier on the points.
For the Map Pilot app, vertical surfaces will have plenty of oblique viewing angle since the DJI camera field of view is 94 degrees. For users that want to create better full 3D models they will have to handle that on their own.
