Fury is awesome! Specially it's realtime features, DOF etc.
But I'm sorry, it's not even close to THIS!
I actually was the original author of Krakatoa and I also was the one that proposed its creation, so I am glad you like Krakatoa.
Fury right now is equivalent in terms of features (but way faster in terms of speed) to the first internal version of Krakatoa, which was used successfully on Cursed (2005), and Stay (2006). The only thing that Fury is currently missing with regards to render effects that is demonstrated in that video you linked to is self-shadowing/volumetric lighting, which are two sides of the same coin.
Although Matthias Müller of course did some awesome PFlow work that makes the animations spectacular, and he also imported some really nice FumeFX simulations.
I'll put some more resources towards Fury in the next little while because I think there is an opportunity for a fully GPU-accelerated self-shadowing/volumetric lighting framework.
Wow! You guys did the Karakatoa?
I think Self shadowing and shadows on objects are absolutely vital. Also, handling the volume texture of the particles. AfterBurn is quite nice on this. XSI Particle volume shader is not that good. In AB you can create a nebula tweaking textures of 5 big particles.
I've said this many times in the forums. As a particle system, ICE is way ahead than Pflow or FumeFx. Lots of options. But hey, it's the final render that matters. Until and unless we get a particle shader/renderer that is competent to Krakatoa or Fume or AB, we have to port to Max and render.
Fury has the promise! Looking forward for the updates.
