CD Projekt are using Umbra 3 for The Witcher 3: Wild Hunt.
“Level artists are there to fill the world with content. Integrating Umbra saved us not only artist time but the time to create and maintain an efficient visibility culling solution. Umbra’s support provides us with the solutions and features that we need”
