No Clue, Idea or Know how - Where do i start?

I know literally nothing about porting or modelling or anything that involves it but i’d really like to have a go at them. The work of Kali, Ninja and Simkas are just 3 examples of the many stuff that i use regularly along with many other ports so i’d love to give something back to the community and to see others using it in their creations.
Edited:

I’d like to do Porting and Rigging. Not modelling, I asked two people i know and they explained.

However i don’t know where to start learning and doing it, thats what i need help with.

Here’s a good starting tutorial. It’s a bit generic at first but gives a decent explanation of Source-related stuff at the end.

Thanks!

Hmm. Only one thing, i’d like to have my productions work in Garrys Mod as well, because i prefer it over SFM and others may prefer Gmod too. Will this work as well for that?

Gmod requires a collisionmodel, and SFM does not. So unfortunately it seems they don’t go over that.

The wiki has some good articles on it though.

Perfect.
