Everything that’s rendered in a game has a shader. This specific shader is a pixel shader, which tells every pixel what color to be, based on how it is lit. Shaders are programs that tell 3D objects how to look. “Lockdown gave us the opportunity to have a look back at things that we hadn’t managed to do previously.” Making the shader “And so we had time suddenly,” Wilde said. That same day, Jay Inslee, the governor of Washington state, issued a stay at home order that would shut down Valve’s Bellevue offices.
Half-Life: Alyx came out on March 23, 2020. The shader got shelved for release, and though Wilde was disappointed, he took it in stride. “But again, it was this distillery level that had thousands of props, and thousands of bottles.”
that probably wouldn’t have been a problem,” Wilde told me. “If there was just the occasional bottle around. “And so immediately, we could see that it was really promising.”īut with Alyx’s release date looming, there just wasn’t time to implement the new shader without causing performance issues. “All the bottles existed as models, and they were all beautifully textured and they look great,” Wilde said. And Wilde wouldn’t be starting from nothing, either: the game was basically done, with detailed assets and a powerful lighting system in place.
There are lots of bottles scattered around in Alyx, but one particular level takes place in a distillery and requires the player to interact with bottles a lot.ĭeveloping a shader that made the bottles look full of liquid would make the level that much more impressive. He made a wine glass shader for the Dota character Jull, which caught the attention of Scott Dalton on the Half-Life : Alyx team. Wilde is a VFX developer, and he was working at Valve when Alyx was in development - but on Dota Underlords. Boozy liquid shader, now available in the latest update for Half-Life: Alyx /Iw9h98pmEg- Matthew Wilde May 28, 2020 Spent a good chunk of lock-down doing this important work.
