Instead of requesting models, I think I should make my own. It is possible because other people can do it, so I should. Can somebody please tell me what I will need to make my own ragdolls and how to put them into Gmod.
What you need to do is acquire a modelling package such as 3DSMax, Maya or XSI (free). You will then need to learn the ins and outs of how the program works and how to use its interface. I prefer 3DSMax simply because I've been using it for many years and have got comfortable with the interface. I'm not sure how easy it is to rig models in 3DSMax and export to Source.
Anyway, once you get used to modelling a few simple things, you would gradually move onto more complex objects such as Humans and Organic objects.
Modelling is not easy. It would take you at least a couple of weeks to get used the interface and learn how to create basic models.
Just Google XSI Mod Tool, and search for some beginner tutorials. Good luck.
XSI is not free, just the Mod Tool. Modeling characters or props isnt something you can really just jump right into, theres a lot of learning and practice involved in it. Look at the tutorials thread that is stickied in this section.
