If i were to play with it, I'd treat the water surface as a standing wave on a string. There are even bubbles below the surface. The video features an interview with Matt Wilde, a VFX developer at Valve who work on Alyx and was the person behind the incredible liquid shaders that were added to the game post-launch. Du hast ein eigenes VR–Projekt am Start? However, placing an entity used in only one engine c… Reporting Issues. Values you would have to set separately for each shape of bottle, so maybe its something fancier like an integral function of the bottles outline. As I expected, this tweet by the VFX developer who wrote it confirms that this isn't a CPU-based physics simulation but instead just a shader. The shader makes bottles appear transparent, with liquid that reacts when you shake the bottle. Then just assume the change in volume from the standing wave on the waters surface is negligable. Or you have a broken mess that looks more like jello. I think that is unlikely and unnecesary because the surface never breaks. New comments cannot be posted and votes cannot be cast. Post useful tutorials and other resources, as well as galleries of cool shader effects.

If I had to guess I'd say its a simple interpolation between preset values based on rotation. Players have noticed that the shader — which is also used in non-booze liquid containers, like water cooler tanks — even appears to create foam in liquids if the bottle is shaken hard enough. Quench your virtual thirst with the ‘Boozy Liquid Shader.’ With a majority of the United States still under lockdown as a result of the ongoing COVID-19 outbreak, Matthew Wilde, Visual Effects Developer at Valve, has been using his newfound free time to develop brand new liquid physics for Half-Life: Alyx and the results are nothing short of incredible. Oder du kennst einfach nur ein schönes Projekt zum Thema, über das wir noch nicht berichtet haben? Während bereits zum Release das Spiel hervorragend in der Virtual Reality aussah, legte Valve kurze Zeit später nach und spendierte den durchsichtigen Flaschen einen extrem tollen Shader, den wir so noch nie in der Virtual Reality erlebt haben. And while I’m sure my life has been enriched by marathoning The Crown and astral projecting out of my body on weekends, Matthew Wilde had a lockdown project that’s a little more substantial: he made boozy bottle shaders for Half-Life: Alyx. This is what it looks like. Half-Life Alyx liquid shaders: Why they look so good.
