Please refer to the links on the Dota 2 Item Workshop Guidelines Homepage for information about couriers, wards, images, music and other types of submissions as well as general asset creation guidelines.
These hero pages contain
Lore for each hero
Budgets for models and textures.
Additional information you need to take into consideration when authoring items, such as specific bones that weapons need to be weighted to.
Hero reference zip files. Some of these have been updated to contain Source 2 format FBX, Maya and texture files of the base hero, item and ability creature models.
These pages only cover heroes that have been enabled for the Source 2 workshop. We will be updating existing hero files and adding files for new workshop heroes on a continuing basis. The icon borders will show which heroes have been added or updated.
