I did a search on this forum for how to make API's from GMAX but I wasn't able to find anything that was comprehensive and really explained in detail how to do this.I found scattered references to Middleman and FSRegen but I have no idea how they work together. Can someone guide me with simple step by step instructions on how this is done?Also, I created a tug with Gmax and I wanted to make the wheels using just a plane. The wheels should look round so i intended to make the area outside the tire transparent. Is this accomplished simply by adding an alpha channel to a DXT1/3 BMP?Thanks again,Enrique

When exporting from Gmax, you must mark the "keep files" option.You must have the newest MakeMDL.You get three files; ???.asm, ???_0.asm and ???.bgl .Then use FSRegen to compile the ???.asm to API.
