For what you want with the gradient, I'd stick with your original setup, unless Redshift can't use that for some reason. I'm not a C4D user, but I'd be very surprised if they didn't support it or provide a similar node. Either way it should be a matter of connecting the output from the ramp to the RS material wherever you…
Thanks for the suggestion. It's a good start, at least I'm getting that "swimming" that I was looking for with world space. However, from what I can tell, it's still stuck with the object's UV map, so the ramp is swimming through the object, rather than the object swimming through the ramp. I need the ramp to exist in 3D…
Hm, you're right, it does look different. I don't have a way to test w/ Redshift in here, so I can only suggest things for you to try. I'd try using the Rotation setting (check that docs page, it's in the Coordinates group) to spin each side so they line up like your original example, something like this (it's a mockup):…
Hi. Try using the Triplanar Shader in Redshift and set the projection mode to World-Space. You can usually find that in other renderers too. They specifically mention the result has the colors "swimming" over the object surface: https://docs.redshift3d.com/display/RSDOCS/Tri+Planar?product=cinema4d
