I try and load my addon into partslab, but it says node_collider exists but hasn't got a mesh. How do I go about creating a collision model, please help. If I do create a seperate mesh and tag it 'node_collider' I get a 'KeyNotFoundException' in PartsLab and it shows me the model of my collision mesh instead of my model. Please please help me, there's no proper documentation anywhere. D:
