From what I know, you can export the mesh or the armature, but not both together. You can use the hammer editor to export the mesh as an object, and use s2fm to export the armature (idk about the animations those seem bugged).

I wrote a little guide for it here: https://www.reddit.com/r/Dota2Modding/comments/4oqksu/guide_for_model_importingexporting_base_hero/

Basically since there isn't a way to decompile vmesh, if you want heroes, you're better off using the workshop reference files here: http://www.dota2.com/workshop/requirements

To create a texture for a mesh, I suggest using this tutorial to learn the basics:

https://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/UV_Map_Basics

You can also save the uv map and edit it externally after exporting it with the mesh unwrapped. From there you can reimport it to use it on your model.

However, this I don't think is the right discussion board. Try using the sfm subreddit for general questions as this isnt really related to the tools.

No problems here. If you just updated the Source Tools you'll need to restart Blender. Otherwise reinstall.

You'll also need to redo your rigging. You should have one armature containing all the bones you want, not multiple armatures with one bone each!

I was going to do 1 bone each since vertex animation isn't currently supported in source 2 and I was using the fracture modifier to get a physx animation of the tower falling apart. But since it has to be skeletal and you can't parent a bone to a vertex animation, I was trying this route.

guess ill have to export each object individually if a full rig doesn't work.

I'm trying to export this blend file for use in source 2 sfm. I used fracture to split my model into objects then attached bones to each object and parented them for animation later (since source 2 cannot do vertex animation like source 1 for some odd reason).

Here is my blend file: https://www.dropbox.com/s/rc5kyim7mt17tdv/workingdeconstructabletower.blend?dl=0

And here is the error I'm getting on export of either format: http://imgur.com/2pmO3FP
