Spent a good chunk of lock-down doing this important work. Boozy liquid shader, now available in the latest update for Half-Life: Alyx

This is a great thread, if anyone is interested I've added some extra context over on blue sky bsky.app/profile/skilful.bsk…

Decided to check out how water is rendered in Counter-Strike 2 Given how interactive water in CS2 is, I expected to see some cell fluid simulation, but turns out they use just a low-res off-screen buffer with flat 2D decals for various water effects. Reminds me of HL2 water :)

For the foreseeable you can find me in the blue place in my profile for my usual shader posts, CS2 stuff and Valve sunset pictures. Maybe see you there. Bye x

I'm not disputing this but was just reminded of when the pandemic hit and we were suddenly working from home - I had to use my old 2014 PC with a gtx 970 which was below our min spec while I was working on the bottle shader. I certainly developed a strong stomach! – at West Lake Sammamish, WA

Half-Life Alyx exists in such a funny niche to me. there's a critically-acclaimed, unthinkably innovative mainline entry in the uber-popular Half-Life series that's like no other video game on the market, and you can buy it from Valve right now. but also it costs $1000

Ever wondered how to set up breakable glass in Counter-Strike 2? We shipped an uncompiled example file with the latest patch. You can open it in ModelDoc to recreate the setup. \workshop\content_examples\breakable_glass\breakable_glass_01.vmdl

I did something similar to this for the caustics in the CS2 water, cheap and effective chromatic aberration

Easy chromatic aberration hack: col.rgb += dFdx(col.rgb)*vec3(3,0,-3);

Derivatives are often overlooked because they can give blocky looking results. The 'proper' way is to sample the neighbourhood in a couple of places minimum but when you have an effect like this which is made up of multiple samples already it's the often the only reasonable way – at Bellevue, WA

This is what led to my Twitter origin story, a tree shader with leaves that flutter gently and brighten a little but accidentally x1000

if you're currently working on a video game, take a short break, pick a number in your code or data files, multiply it by 1000, and post the results

Daughter's birthday - she wanted a chocolate mousse cake but got the words a little muddled when she asked for it. And was very confused when she saw what we made her. Anyway, enjoy your chocolate goose cake Ada x

This is great, families can now share games in a common pool - accounts aren't locked when games are being shared as before so multiple family members can play games in the family pool. Congrats to the team on shipping this!

Hello! In a surprise move I'm going back to work with my friends at @valvesoftware this month. Having a stint at being independent has been amazing, but it sounds fun to work with people again for a bit. Here's a reel of a few things i made during this nice time in my life.
