We’re excited to announce the models and assets that made Warcraft III an amazing universe to explore are now available in the StarCraft II PTR.
This brings over three thousand new materials for the amazing Arcade development community to work with, including new hero models for the 4 primary races, all of the original Warcraft III models including neutral creatures and their sounds as well as doodads, structures, spell effects, ambient sounds, music and custom user interfaces for each race.
Only a portion of them are updated. The majority are just 1:1 exports of the wc3 meshes. You will probably want to backport them anyways, because their particles are pretty dreadful.
Probably. Then they fired the one intern working on it, released all their "new" content and got praise for the 2-3 mappers left still making tech demos for the game.
