Working for the Robot Week, I'm searching for suggestions of how to improve this little thing. I'll add bird flaps as soon as I can.

Thanks a lot for the answers :D. I was just trying to keep everything organizated for the beginning in a good folder structure, for the maybe day I'll be able to do a good short with my characters. But, for now, I have to practice a lot.
Thanks again.

Hi, I'm new here. I'm trying to learn animation by using the Source Filmmaker and seeing a lot of tutorials, and I'll try to start to cooperate here as well. Thanks for read. Now the actual question.

Maybe this will be overkill, but, I want to keep the models I download separated by author, so I remember who did it, but I don't know how to do it. I was thinking in just create a new folder in the folder estructure, but that doesn't work :(. I'm guessing I can create new mods, but I don't know how. Any ideas?
