Really like DroneDeploy and I've been evaluating it against Pix4D. The latter is about as user-hostile as software can be but it does have some killer features - and the flythrough/animation function is really useful when dealing with clients.
If the functionality exists, I can't find it on DD. Or has anyone here succeeded in creating flythroughs using third-party software? Blender and Meshlabs don't seem to work for me so all help gratefully accepted!
