Under ambient animations in Summer's Gone you mean cinematics? They are beautiful, but to be honest, I would prefer that devs instead of creating animations, making game faster without them (or with minimal amount of them). Animations aren't important to me, beautiful renders and good story/writing are enough. Summer's Gone have most beautiful renders I've ever seen - work with lighting, those close-ups on eyes...
I think the photos are quite taken out of context; maybe that's why you didn't quite understand the intention, but that's okay. I think it's quite difficult to understand what it's about without the rest of the stuff. The time for these shots is in the evening, when the sun is setting, but these two photos are not the original ones found in the game. In the past, I've rendered a lot of stuff, and a few days later I started seeing problems and had to redo it. So what I do now is rather render a couple of images (I don't think any HDRI was used on these two, just "Dome and Scene") and always come back to them later and make them into the final version. I wanted it to be a little darker and have cool colors for these shots. Through what is discussed in the story during these scenes and what music is playing in the background, it fit quite well for me, and in the end, I was quite satisfied. But, as the saying goes, "100 people, 100 tastes" hehe. And you're right, I think Ocean does a great job, but it's not for everyone. I know many players who don't like the visuals, but luckily I don't belong to that group.
I like camera angle on s397, but I think both renders are too dark, light source on s413 (it's sunset?) looks too fade. But anyway I like them too.
I'm not very good at explaining things, but 99% of my pictures have the sky as the main light source. Of course, such light does not reach everywhere, so then I try to illuminate it with the help of classic "spotlights", if necessary.
emotional romantic scenes
To be honest, I don't really enjoy classic sex scenes anymore. Especially lately, I've found it boring because in every game, it's the same animations made from loops for $10. I didn't even create any for Chapter 1, because I'm not yet experienced enough in animation to allow myself to do something like that, but maybe I'll try something in the future. The main thing for me is that those scenes arise naturally, and if the sex scene doesn't suit me, it won't be there. I don't want to do something I'm not happy with just to satisfy someone's taste.
Anyway, thanks for taking the time to write me your opinion; I appreciate it!
