I'd love to export a fluid sim from RF|C4D and have it rendered in Keyshot (liquids look great in KS). But I can't see any way of getting the app to import an object sequence. I'm sure one of the team could knock something up for this – all it needs to do is load object.001, render the scene, replace it with object.002 and so on.
If I bake the sim out as a single Alembic (which I currently can't anyway) the file would be massive!
Sounds like the "Render Images" script or a slightly modified version of it is what you need.
