It’s really fun playing with render engines, it’s almost like trying different lenses: each has a distinct character.
I have had the chance to use Arnold lately and it’s a lovely renderer: the IPR is fast, the integration into Cinema 4D is really well executed, working with the materials and the node window is really pleasant, and the AOVs are the icing on the cake!
AOVs are so well integrated and so easy to use, which to me surpass even C4D compositing tag (which is already one of the best features C4D comes with).
In the image below I played with some soft body simulation, composited in Affinity Photo and created the basic vectors in Affinity Designer.
I think this could be fun to animate too.
