I think that what we can all agree on is that we want to see the internal anatomy. Everyone seems to have something different in mind. Can't it all just be solved by giving the character models a detailed internal anatomy? It doesn't have to be anything CRAZY, but enough to scratch the itch. That way any user could just pull back the opacity of like the subject's skin, and then their muscle opacity, and then their bones, etc... People could see whatever they wanna see. Use a free floating camera that can go anywhere, in anything, and out. No restrictions. Nothing left out.
Wouldn't that satisfy all fetishes?

It doesn't sound too hard to tackle from a development standpoint either. The big hurdle is to design the internal anatomy. Maybe rendering that in game would also be demanding... but maybe organs don't need to render unless they are being viewed.
I dunno if I'm failing at trying to make this idea easier on Fek... But the easier it is, the more likely it is to be implemented.

It would be an option, of course. I don't expect any fetish suggested to be required, or unable to be turned off. I sympathize with you; it's a difficult fetish to understand, but it doesn't need you guys pushing it down.

*slaps forehead for not suggesting this before*

I guess that console command is hopeful, but for the future I hope there's more support for hypers. hypers don't just mean big to me. In my mind they're totally hulked out and veiny. You know?

I just wanna see internal organs and the like. Heart pumping, lungs filling, genitalia juicing and being filled...

huh...

:'D Thank you.

Sorry. I mean having a subject with a huuuuge heart. It's a cardiophile thing...
