Hi guys, new member here! I'm an engineering student from São Paulo trying for the first time to make a mod: my university's Formula SAE car. The physics are pretty much done now, and I've turned my attention to graphics. This is my first time working with 3DS Max, 3DSimED and the rfactor dev tools, and I'm having a hard time understanding the .gmt structure inside the .mas files. In my search for information, I've tried and failed to extract the .gmt files from the original cars and later found out that they are encrypted -- fair enough. I then downloaded a mod and tried to extract those .gmt files, but still no luck; 3DSimED tells me they are also either encrypted or corrupted. Finally, I tried to make my own .mas containing only the steel frame of the car, and the result was, unsurprisingly, a failure. GSCE told me it couldn't write steelframe.gmt to memory and displayed a boxy low-poly model that apparently exists as a backup for this kind of situation. So I've got a few questions: what am I doing wrong? Are the rfactor tools not compatible with GSCE version of gmotor2? Do people costumarily encrypt mods? Should I be using different tools? And finally, why can't I post in the mod section of the forums?
