Depending on the files you started with you should be able to get an importable item. However, trying to do a whole costume in one step is not going to work. To get it 'poserised' you probably want seperate boots, gloves, cape and helmet. Each will need textures, bumpmaps, transmap etc. You'll certainly want some morphs for posing and adjustments. Fortunately some very nice people have done all this already. Try the starwars freestuff at JHoaglands site: www.vanishingpoint.biz
