I am looking to make some models of half-life mod (Natural Selection) to bring with me on my trip in a few months where I am going to be stopping by their new offices and giving them as a surprise gift. (just in case there is some legal issue with doing this?) I have some of the character models from the HL mod in a .mdl format. AccuTrans3D states that it can open .mdl files but when I try it on the ones in the game it says the file type is unknown and will not open (guess HL uses the same extension). I downloaded a Gldsrc model viewer (Jed's) but it can't export the model into any other format. Is there anything more I can try or will I need to look at getting the original files to do this? I can get them, it just might tip them off I am up to something Thanks I've attached one of the models just in case anyone wants to try an idea.
