Yes, they plan to porting the legacy C4D shaders as native redshift shaders (i.e. not only available to C4D but to all DCC).
I proposed to them to implement already the C4D shaders as temp solution so we can already use them while waiting for the native one. It shouldn't be that hard since the code is there.
But nope. Probably take 5, 10, 20 years from now? lol
At this point, it is really senseless to think that C4D gets an advantage in redshift because it is acquired by Maxon.
Arnold, Octane and even Cycles4D gets more or less a better integration than the supposed to be "native" Redshift.
Octane won't adapt to the native nodes editor because Maxon took a long time to provide the API that they already made their own updated nodes editor.
And to think that, ONLY C4D where you have renderers implement their own node editor. It's a mess.
It does not happen in Maya, Blender, 3DS Max, Houdini etc.
