I used to mod a lot like 4 years ago, but lately I just can't find enough time to mod as much as I would like to. I only get time to play around with some of the new tools.
I worked with most of the engines out there, mostly doing levels.
But I also have made a few characters, weapons and vehicles. With animations and code included.
And I pretty good with 3DS Max, Maya and Photoshop.
