My crap mod won't load.

[mincespy]

I tried to make my first mod in blender. Just a simple object. Does anyone know why it won\'t load?

I\'m going to get showered with things I did wrong now.

Your dumbbell model is missing a collision mesh.

From the blender tutorial:

A collision mesh

The collision mesh sets the shape the game uses to calculate collisions, and where parts are allowed to be connected. The game only uses one collision mesh per part, so only use one object in your model. Add a new object via 'Add:Mesh:' then selecting the shape of your choice (usually a cube or cylinder). Select the object (right mouse button by default) and then go to 'object' then rename it 'node_collider'. Remember to add a material and UV co-ordinates to this object also!

Oh. Ok.

I feel... stupid.
