Weird environment map

Hello. I have a vehicle mesh that mounts various parts upon damage. On the whole, the white parts of my alpha for the vehicle are getting displayed as part of the environment mapping. The way the environment maps are getting displayed are not consistent either. One mounted shape displays this huge dark blob for my e-map ( it almost seems like the sky texture is getting scaled really big and then mapping itself onto my car ), while another mounted part reflects the sky texture more realistically without showing a huge blob. If I knew how to post a screenshot here I would. I'm using unmess.DTS too. Am I doing something wrong?
