It has 153 vertices and 262 triangles. So it is quite low poly, but that doesn’t matter because ingame the models are small anyway. It is still untextured and I will have to see how it looks ingame to decide if I will keep this model or replace it with another.
As a bonus, I found out how to add an armature to a model in blender and how to animate it. I also encountered multiple errors in unity while trying things, including error related to how unity uses fbx import prefabs. The biggest annoyance is that unity replaces parts of the prefab in the scene but not all of it. For example, it replaced the animations, but not the mesh and bones itself which led to multiple errors.
