sure tell me what's the issue, sorry for answering 2 days late BTW. and didn't test them properly on the unity environment.
sorry for late reply. when i imported it into unity all the weapons are sort of become flying especially bow as i need only bow and arrow. so i tried it to open it on blender after exporting from blender (disabling all unnecessary things like sword shield etc ) when i imported again my arrow is not properly imported and i got some problems with animations . And thanks for your help!
