Agreed.
And in case Insydium did not need any more motivation, there is Reactions (TFD V2) in beta which is also GPU based (though not sure real time like Embergen). The big detractor to Embergen is that it is standalone which means importing cameras and objects and exporting VDB channels for rendering in Octane in the host DCC application. That is a bit cumbersome....kind of like working with Lightwave's modeler program and having to always jump back and forth between it and the layout program. In short, bi-modal workflows are not always the most efficient.
If Insydium was GPU based and totally integrated with Redshift, then that would be huge for C4D. Honestly, Maxon should buy Insydium and then unleash the Redshift GPU programming wizards on XP to speed up the development of a GPU version. Having a native GPU based multi-physics fluid/cloth/grains/smoke/fire/dynamic particle system within C4D capable of scaling to massive particle counts plugs a huge number of holes in C4D's toolset. It not only strengthens C4D but kills any desire for anyone to consider working with Embergen. And considering that Embergen requires Octane, removing the need to use Octane for Embergen because everything exists natively in C4D helps also helps Redshift.
