I am a user of Gmax and i was wondering if i could use the models i make in there in Hammer. Gmax is the freeware modding version of 3ds max for those that dont know...
You can but the main problem is exporting them. Last time I used gmax it only had one export option which then couldn't even be imported by 3dsmax. You'd have to use a third party plug-in to export to a format which can then be imported into something that can export to SMD.
