Hi fellow modders! I already posted those request in MTW2 Tools and Tutorials section without any effect.
Seems that problem is easy for the knowledgeable one. I took slinger germanic unit model for primary sling wearpon (according granted permission) but sling is invisible in a battle. Please, heal this unit, it's very important for my mod! I will credit those who will help with separate line in credits!
