While Daz3d has a plugin for fluid simulation, it is very primitive, because Daz3d is not designed for such features officially. For a game where milk is a central theme, fluid simulation is rather important.
Well, when it comes to fluid simulation, of course, there is also animation. So, this is a chance to test out temporal denoising, which is supposed to lower the render time of animations by a lot. But, as it turns out, it's not a magical solution either. If you can't see the video clearly, it's actually a stream of milk falling down on a pool of milk in a glass tube. I wanted to see just how few samples, or how low quality my renders I can get away with to show an idea in an animation.
As you can see, there are quite a few problems. Firstly, there are weird vertical lines on the glass. I don't really understand why because the preview image doesn't have this problem.
Secondly, even denoising has its limits. The video is comprised of two parts, which were made using different methods. The second half of the video contains noise even after denoising.
Regardless, these techniques are still very useful. I have seen how long people say their animations took. In a behind-the-scene backroom video, the creator said 40 minutes of animation took him 39 days of render time. That's insane. That's why I have mostly avoided animations in the past. But with the denoisers, I can make animations in much shorter time. Also, there are other kinds of fluids than milk, right? :P
Oh and, this entire scene was made by me in Blender. Although it's very simple, now I can finally make environments that are designed around the theme of the game.
