Aha, interesting! I read 3dC in your text and first thought of C3d - that is Cinema 3D (and looked completely different from what I knew). When I looked it up I found https://en.wikipedia.org/wiki/3Dc, had been disappointed on my little research, and had been thinking of my first impression of Lightwave again. Anyhow, I've been more into 2D compositing back in the days, speaking of Fusion, Aftereffects and alike. A often composed 3D art into shootings. Had been fun!
