Liquid shader is back for the CS2 charms, this time with not-fake physics and not-fake refraction!*

*it's all fake, it's a videogame

The Grandaddy show in Seattle last night, they had a slideshow of old photos taken from various places on tour mostly. The headline got a chuckle from the audience when it popped up. It was followed by a cool horse.

The caustics from the interactions come from sampling the buffer again, this time reprojected to fit the underwater geometry from the direction of the sunlight. It has its limits and the fade happens when you approach the edge of the buffer. It's also refracted in the same way as the frame buffer.

The blue channel was originally just to add silt being kicked up but ended up used for more general long-lasting interations. It's used to carve out a path in the surface debris and the normal derived from this channel allows us to push the UVs apart a bit so it feels like you're moving it around.

Genuine question @dominos-pizza.bsky.social : Is that stuffed crust or classic?

We had fun making some rain fx in the new CS2 de_train, maybe I should a breakdown?

More recently I worked on the CS2 water and effects. I hope to share some more CS2 (and other) shader work here (and not there) in the future.

I do often tend to work on liquidy things - this was the water test we did at Campo Santo pre Valve move

The Half Life Alyx booze / liquid / bottle shader which I worked on at the start of the Covid lockdown and got a ridiculous amount of attention
