I'm wondering why I don't see much 3D art in the portal? I read that there's a rule against Source Filmmaker, but beyond that I'm not sure. I've been producing a lot of art in Cinema 4D using Kitbash3d and Reallusion characters and I'm hesitant about uploading it. Thoughts?
Here's an example of the one I just finished.

3D art in the portal is what I would call uncommon. It's not a familiar medium to everyone and takes a whole bunch more work for a one time use scene compared to doing a one time illustration. There's also differences in styles and execution of 2D art that is a reason for more 2D art in the portal. I'm pretty sure SFM is allowed as a renderer, but it's in general kind of awkward when you're just using pre-installed models and locations and just pose the character and post that. Being creative on the other hand with using SFM, such as importing your own models and scenes, is better and not so looked down upon.
In summary, don't post a TF2 scene that you just posed the characters. In your case, I think you'd be ok. I assume you designed the scene in the photo above and that's the focus. You just might want to credit the character model.

Thanks for the info! Even though I didn't design the original models (which I paid for with a royalty free license), I put a lot of work in to modifying them and creating assets to decorate them with (neon signs, textures, materials, etc) so I feel it's enough to call my own creation where I didn't just copy/paste, then place a camera. I guess I'll post one, then see if I get chastised for it haha.
