Continuous co-operation effort between Sitni Sati and cebas resulted in amazing global illumination optimizations for rendering FumeFX 2.1 using finalRender 3.5 GI. Speed gains are truly amazing and rendering FumeFX scene with Skylight can result in over 10x faster rendering times ( 2 minutes, instead of 20 minutes !).
From the artist's point of view, this means that very high level of realism can be achieved using global illumination at reasonable rendering times.
Currently, QMC and Adaptive QMC algorithms are fully supported, while Harmonics GI support is partial.
