So.. can you put Mario and Sonic in the filmmaker?

[Zhead]

I know there are source models that exist that are not owned by Valve.

On the top of my head there's a Mario, My Little Pony and Sonic models that exist in Source thanks to Garrys mod.

So can you put such copyrighted models or it's just TF2, L4D and all other Valve models.

I'm pretty sure you can put anything custom in it. I am going to try and do some stuff with Sonic characters if possible.

If you create such a character (or find it somewhere), then yes. Correct me if I am wrong.

Yes, as answered in the FAQ :
