Carrier

Notes: I have tried a couple times to convert ship models from Homeworld to be used with Gmod (half-life 2 mdl files). I've been able to do it fairly successfully using a few different methods but always get tired of it and give up. My main concern is the turrets; I want them to move but I'm not sure how to make them move so I don't. This is a Kushan Carrier from Homeworld in a model editor, this image was saved to check the look of that colour pattern mostly.
