Assuming that is a rendered output from godot it looks like your bump map might be too heavily compressed, but texture coordinates/alignment seems fine to me.
What file format did you use to save the bump map and what texture import settings might you be using?
For the zoom/navigation you will have to implement a player-controller/game logic. Seems to me you likely have none right now? That should only affect the exported game as well as launching from within godot, but not the editor viewport.
