Mod Creators are permitted to use all ARK Survival Evolved assets within their ARK Survival Ascended Mods. The one exception is that Mod Authors may not reupload Official DLC maps as mods.

Mod authors are welcome to import assets from the ASE DevKit and we encourage it if it makes your development efforts easier.

Animation BPS do not support using montages in the animation graph. in ASE this was possible. if you import any Custom animation blueprints that had montages in the animation graph it will crash.

It's official from the corporate top-boss: creators can use all ATLAS assets within ASA mods as they see fit! 

Only for use within ASA mods, of course.

We're going to be updating the DevKit with all the latest content from the map, as well as the new ARK: Bob's Tall Tales DLC. In the past we would have restricted access to the DLC content for some months via the DevKit, however we'll be including it as soon as possible with this release. Creators are free to mod the content/gameplay systems that derive from ARK: Bob's Tall Tales as long as they continue to maintain the built-in ownership ruleset associated with the new additions. We'll be monitoring mods for how they use the content/systems and any that have modified the permission-ruleset will be removed.

Exceptions:
Exceptions have been made for the following content,  these systems are allowed to be used in mods without  enforcing the ownership of BTT, possibly with some restrictions.

Dino Traits System:
Mod can modify and make available use of the Dino Trait System without enforcing ownership of BTT.
Mods MAY NOT use the assets for the Gene Scanner or Gene Storage (gene Infuser) or other gene structure Items/Structures or make them available without enforcing BTT ownership.
The system itself may be exapanded , modified and mods may make their own versions of the items and structures use in the trait system, they simply must not use the visual assets or  make the existing BTT versions available without ownership.
