Mykhailo Moroz, a Lead 3D Research Engineer at ZibraAI(fluid sim add on for unity), has been working on enhancing the add-on and has lately exhibited this great job improving foam, adding partial foam occlusion from liquid absorption, and improved foam physics.

The creator stated that this would be a zebra liquids pro feature, and that you will have to wait at least a month to get your hands on it.
Have a look at the previous improvement work shared by Mykhailo.

Did some improvements to the WebGL water caustics. Now I compute the derivatives in texture space(with a precomputed texture), instead of ddx/ddy. It produces waaay smoother results, on top of that I also use a 512^2 caustic mesh, which looks really pretty. pic.twitter.com/NzYM5lsBtW

Improving Zibra Liquids foam generation, still lots of work ahead. Specifically the foam is not yet occluded by the liquid, making it look way too white pic.twitter.com/ehFt3jE7Mq

I've been playing VRChat recently so decided to make a water simulation shader. This is basically a carbon copy of the WebGL water demo, but in VR pic.twitter.com/4cBHzpMmeY

Check out this really cool use case of zebra liquids shared by one of the users.

Back to liquid physics in AR.
