I'm not sure where the best place to put this so don't beat me up.
I have been playing tremulous for a long while now and I am getting tired of seeing the same human model over and over again. It even caused me to shoot at the wrong person at first when we all spawned with rifles at transit (least fav map for multiple reasons, why no armory start?).
I've done some modeling pojects for Jedi Academy over the past year (mostly recolors) and made a simple recolor test for Tremulous. Interestingly, the model variable in-game by default is sarge but when I change it to mine, nothing changes. I checked the files in my pk3 for path errors and other stuff but in the end, all I found out is that my model could be "aDrunkAndHomelessBum" for all the game cares. I find it odd that the game does not get an error when I change it to something that doesn't exist.
I then looked into the class system and saw that model stuff works there. Slightly annoying but I got an idea from it. I then attempted to make a new human class using my greyperson for its model base. Well, in order to change classes as a human, you have to be dead. When you are dead, you have to know what your starting weapon is. A vicious circle. Now, as an alien I attempted to change classes to human_base to see the error message like "you cannot change to this class." With that in hand I tried to change to my greyperson class and got an "unknown class" exception.
If anyone knows anything about classes please help me because I have a few ideas for this but don't know what all needs to be done. In the meantime I'll keep looking.
