hi guys, so recently just got interested in making a custom character model for Luke in left 4 dead 2. i downloaded the OBJ files but i can not understand how to make it works. i googled the tutorials but it seems like it i too much for me, i am not a computer whiz so... if someone could help me, it would be much appreciated!

here's the link to the OBJ files. http://tf3dm.com/download-page.php?url=luke-79449
