They look impressive, good work! My one piece of advice is that you should try to stay away from fedora-like hats since we have like 6-7 of them already in-game.

I don't really know what's up with the GUIstudio compiler. I haven't tried using it since the steampipe update (which was during the beta import tf2 update), so as far as I know the update broke it. You could always just manually compile your models using valve's studiomdl compiler.

They are only 2 files. Each image is made up of 4 channels (Red, green, blue, and alpha). https://dl.dropboxusercontent.com/u/10100459/BlenderImages/alphachannel.jpg

Photoshop is best for editing channels. I'm not sure how to do it in any other image editing software.

Well it's always more fulfilling to do the whole thing yourself, but if you really feel like you could use help, there are ALWAYS people available to texture your models. I know some people do this for a living basically. The downside is that you'll have to split the revenue if it ships.

My advice would be to look at how other metal looks like in the game. Check the vtfs in the dota 2 vpk files. You'll need GCFscape to open the dota 2 vpk (\steam\steamapps\common\dota 2 beta\dota\pak01_dir.vpk) and then look at how other people set up their materials. Unfortunately we don't have access to the .vmt files for dota (like we do in TF2), so you're going to have to use the _masks to get the right look.

Yeah it looks much better.

Not bad :) Looking really good! Make sure to spend 2 times as much time texturing it as you did modeling it! It's a good rule of thumb to get really good textures. Here's hoping it will turn out great.

This looks incredible!! I would totally use it, dude!

I'm not sure what your problem is. Can you describe it with full sentences?

I already rated it up, haha! I think it's great and has a decently high chance of getting in this winter.
