[Solved] How to animate objects?

[HimbeerserverDE]

I'm trying to create my first simple animation in Blender 2.79. I'm using the official MT B3D exporter plugin. I want to animate a cube and make it change its position by 1m. In Blender it is working correctly, but in MT there is no animation at all. I'm pretty sure my animation is the problem because if I export downloaded blender files the animations work.
How I exported:
1. Object mode
2. Shift C
3. A (2x so that everything is selected)
4. CTRL J
5. File > Export > B3D
I attached a zip archive containing my init.lua, .blend and .b3d files
I have looked at solutions on the forum but none of them worked. I'm probably missing something obvious.

I spent way too much time trying to figure this out, for such a simple solution.
You have to animate the armature in pose mode, simple as that. Your animation is in object mode, and when exporting that get's lost.
