I have made a ton of progress since the last devlog. First I added a simple but good looking sky shader which has clouds and a sun, and then hooked up textures on the loaded models so they aren’t just basic colors anymore. And I also added support for loading your own .glb models and they’ll work in the sim. Relatively small changes but they made the scene look a whole lot better and more interactive.
Audio was the biggest change and took the most time, but it was also the most fun. There are multiple layers to it, like the general ambience is pretty much layered water sounds like water flowing sounds, foam sound, lapping sound, bubbles, etc that crossfade based on how the fluid is moving. External objects also create sounds like you can hear them splash in and out of the water or when heavy stuff sinks there is kind of a low rumble. There’s also sounds for water splashing on itself, objects colliding around with other objects, etc. There is also a cool underwater effect where if the camera is inside the water stuff get’s muffled and stuff which is really cool. What’s good is that everything is driven by the physics so everything is dynamic and nothing is being faked. Like each sound is created for a reason.
After that I added wind to the sim. Like wind is created using gusts which are scheduled procedurally, so you get calm stretches and then a burst of air. I also added another interaction too. You can now create vortexes using V + left click which is kind of fun and adds more interactivity.
I also added sculpting to the terrain. Now you can change the terrain to your liking by using different brush modes like: raise, lower, smoothen, flatten. I also optimized particles check with the terrain especially after stuff had become more dynamic though that was pretty easy to do.
Some other small polishes I did was to clean up the settings panel thing among other small stuff.
The sim is basically feature complete at this point, so next up is cleaning up the UI and then creating a good README.
