ZibraVDB - A real-time VFX compression tool now with a free personal license
ZibraVDB is a compression solution developed by Zibra AI to make film-quality volumetric visual effects practical for games. Released last year, it allows large OpenVDB-based effects to be integrated into game projects without major sacrifices in quality or performance. Although OpenVDB effects are common, they are rarely used in games because of their large file sizes, poor real-time performance, and the need for time-consuming conversions. To render effects in real time, artists typically simulate volumetric effects in tools such as Houdini or Blender, then export them as flipbooks, which are 2D texture sequences that approximate a 3D effect.
