I have a feeling that's not quite right
XNOEdit rendering cht_agent01_speak.xno with the environment map completely overwhelming the rest of the shader.

First recomped shaders working in XNOEdit, entirely without 06's engine!

Things are rendering again, this time not through WGPU! Now to figure out if recomp'd shaders are doable.

Isaac @isaacmarovitz.com · 18/09/2026
Tangentially related to recomp, I got C# bindings for Plume working! XNOEdit can now use the same RHI for rendering as the recomp itself which means I can hopefully get retail shaders working :)

Complete with the unobfuscated JavaScript with the prompts still in it...
Vibe-coded JavaScript comment that reads

"    // New Game / Load reload the page with this flag set. The main bundle
      // won't run for a while (it's the whole game), so the title screen must
      // be suppressed BEFORE first paint or it flashes through the reload.
      // Exit to Title uses a sibling flag so its reload starts covered too,
      // but leaves the title in place beneath the veil.
      // the bundle parses for a good beat AFTER first paint on cold machines:
      // until main.ts is actually running, the title chrome would show
      // half-dressed (frame and buttons, but no logo, no ocean art). This
      // class keeps the chrome invisible so the player waits on the calm
      // gradient sea alone; main.ts lifts it when the artwork is ready and
      // the entrance choreography can play as one piece."

Plume has gotten some nice cleanup + improvements to Metal. No more memory leaks! (Especially in the RT64 recomps)

Yeah, after this shit show, I will be migrating all of my sites *off* of Bun. I can't trust a project that decides to redo the entire thing with 1 million lines of AI-generated Rust code in a single commit.

So it turns out that symbols for some of 06's most elusive and complicated systems have been sitting on the X-Hax server since 2022. It cannot be overstated how helpful this will be for the recomp and future modding efforts. 🎉
