Looking for someone to help me finish an E350 ambulance. I have gotten it into gtav but am running into all kind of issues. (transparent tires glass changing textures body is transparent.) I have no clue what I am doing wrong. ive tried tutorials. Attached is a copy of the ambulance files unlocked. https://mega.nz/#!J90CFDCS

I have been working on an ambulance for about 3 weeks. I have gotten everything the way it should be set on the model its self, but I am not that talented in zmodeler 3 as I am with zmodeler 1. everything is set up on the model, I believe I have all the textures I was going to do done. but I cannot get the materials or the dummies set as I keep getting confused and lost. ive tried tutorials but they are all on youtube and not a full step by step on the process. I would greatly appreciate the help. this is what I have been working on. http://www.lcpdfr.com/forums/topic/80469-wip-2005-ford-e350-ambulance/ Shoot me a pm if you are interested.
