Small Size. Mighty Results.

Opsive is a indie company based in Raleigh, North Carolina, founded by Justin Mosiman and Sarah Watson. Justin and Sarah started to develop iOS games in 2008 and released two titles. They then switched to developing tools for the Unity Asset Store and have been doing that full time since 2013.

Opsive’s pinnacle assets on the Asset Store include Behavior Designer, the Third Person Controller, UFPS, and the newly released Ultimate Character Controller. Opsive quickly gained in popularity on the Asset Store because of the quality of their tools as well as the support provided. Opsive’s assets have a five-star average rating out of more than 2,500 ratings.

In 2023 Opsive released Omni Animation, a revolutionary AI generated animation service. Omni Animation is a deep learning network capable of producing high fidelity animations. It is designed to speed up your animation workflow and as a result, saves you time and money from creating new animations. Omni Animation is perfect for personalized hero characters, NPCs, crowds, and motion matching. More information can be found on
