Honestly... I'm pretty bad at animating myself. Though people tend to use Maya to animate for Brawl... I don't know if it could work for DOTA, since it's another game and all, but that's all I can tell you. There's a tutorial in the A/A Section that shows you how to animate with Maya. You should go there and have a look.
Hope that helps.

Any help appreciated! I'l try to explore Maya animation. Thank you.

Making it myself. And also, I'm doing Archer, but also Saber and Dark Saber.

I can only wish u luck. I just asked you because wanna know some info about export animation from UC, but it seems impossible =(
So one another question - what soft did u use for making animation? I tried to use Rider model + Biped skeleton in 3ds max, but my low skill make her like a wood dummy.

So i wondering what is best way to animate her more... better. Of course skill is requied (i understand that), im just unexpirienced in animation, but maybe u can also give me few advices (about soft or something)? I would be very grateful!

It seems that this thread was dead... until you necroposted...

Anyway, I'm working on a moveset for Archer, if it can interest someone here, or somewhere else...

Excuse me for my bad english, by "moveset" u mean animation for character? If yes, did u export it from game or making it by yourself?
