Video game quality is no longer limited by console hardware performance. On the contrary, the current generation of consoles are starved for high quality content that is stressing the capabilities of artists using proprietary tools whose features are lagging behind the needs of the industry. Your next-gen gaming experiences are being held back for lack of innovations in the tools of a very few companies with bloated, expensive products. The video game industry thrives on innovation and creativity and is searching for solutions! Open source software is prevalent in computer graphics today. As game production becomes more expensive and complicated, it's valuable to quickly combine available software packages to support novel tool pipelines rather then creating an entire pipeline from scratch. Our panelists are primarily the project managers for open source projects and are here to discuss the motivation, collaboration, and integration of open source tool pipelines that meet the growing demands of next-gen game developers.
