A common theme in the responses is that renders allow for greater creative freedom; which, while I agree in theory, I have yet to see in practice. Most of the scenes in games consist of two to three characters hanging around living rooms, backyards, or offices, and just talking. And the sex are mostly just the ubquituous oral, vaginal, and anal. There are no crazy physics-defying poses (at least not intentionally) nor are the scenes composed in such a way that'd be difficult or impossible to replicate in real life--nor hard to google, e.g., redhead blonde modern living room. Skimming through the previews for popular games here, I don't think there are any scenes that wouldn't have a superior photo replacement.
2 problems. 1, you're not playing enough games. 2, this doesn't address the matter of consistency. If you only have sex scenes in your game. Sure, you could replace it with porn. But you'll never have any connective tissue. Parental Love has the characters go on a hike and have a picnic, as a family. So in order to show that scene, I'd have to choose 3 porn stars, 2 that look like they could be my daughters and 1 that is more mature, and a male who go on a hike and have a picnic. Simply put you're never going to find that. Especially not when I have to also take them all out to dinner at a fancy restaurant a day later.
It's also true that renders allow for unique characters. But again, it's simply not the case in practice. I don't play many games here and even I've already seen the same characters (down to the outfit) appearing across multiple unrelated games. As I understand it, models are mostly bought and not created ad hoc. If this is the case, surely there are far more porn stars than existing 3D models to choose from.
Again, you're not playing enough games. There are a few that are definitely the same character recycled. A lot of people have recreated D from DmD. Her look is actually relatively custom. She is not a base model, but an amalgamation of a few models with sliders changed, If I recall correctly. Also, if you're not playing enough games you might run into a lot of new games that are just using base models. However, I'm a part of a 2 development teams, both teams have completely unique characters.
Again, consistency is still an issue. I don't care how many scenes the porn star you have chosen is in, if you're using her scenes you're limited in scope.
Given that people are complaining about renders taking upwards of hours per image. And googling, no matter how high the standard for consistency, would take at most a fraction of that time. 3D renders seem like a lot of unnecessary work for an ultimately inferior product.
You've never complained after a days work before? Just beccause the work happened doesn't make it not worth it.
I get that you like porn images. However its not worth the sacrifice. Go check out Game Legends. It is a short Kinetic Novel I was responsible for writing. The models are recreated from BB *again a game with really custom models, our artist was simply a fan artist who had remade them. He had already made the images, and as a result I was limited in my writing by the scenario he had laid out. It isn't my best work as a result. It is still hot as fuck imo, but it would have been better to cater the art to my writing than to cater my writing to his art.
If we made the switch to writing games and using porn images, we'd begin being limited to writing scenes that fit the porn images and never again be allowed to explore anything outside the porn set.
Also, you'd never be able to make Coceter Chronicles without art instead. Demons and fae creatures and futanari women abound. That game is definitely the best game I have played. I know tastes are subjective, but the fact that the game managed to immerse me in a fantasy scenario without excess exposition and also fleshed it out well enough that I could totally, if I wanted, take and use it to create any story within its world, makes it an amazing feat for any world, but especially a porn one.
