So recently, DOTA2 had an update with an improved hammer(in the authoring tools section) here's some pics
Much larger map size? Guy says he didn't compile this though
#
Currently it only works for dota 2. Looks like an early version of Source 2 though.
Importing models also seems to be waaay easier with it
More giant maps in S2
Can make models into editable meshes
"It's not source 2 m8, i swear on me mum"
Best evidence we have,
Anyways, thoughts?
