Years ago, I was a purist when it came to creating 3D CG: I would restrict my projects strictly to a purely rendered output from a 3D CG software, mainly, Poser (from Poser Artist and up). I made it a personal challenge to learn how to set up scenes which required no further post-processing. I considered any form of postwork as touch-up for a bad render. I also looked at purely 3D CG rendered work from other people who did not do post-processing to their rendered output. That's how it has been for me for many years.
In more recent years, I decided to move toward creating images for use with visual novel otome games. I wanted to stay fairly within the canonnical aesthetics of Japanese otomoe game character design - fluffy gorgeous 2D styles. I am still in the process of acquiring a good cross-over 3D-2D visual style, so this is an on-going exercise for me.
It is a bit of a full-circle as well. I actually learned how to create 2D images with early versions of GIMP, and now I'm back to 2D image creation using Clip Paint Studio Pro and ComiPo . Took me 25 years for the round trip.
Anyway, I will use a mixed digital media approach, going forward.
