    Hi! 👋 I’m having a problem with Open Brush on Pico 4 — when I launch it, the logo shows up, then everything disappears and I just get a gray screen. I tried restarting the headset, reinstalling the app, and other VR apps work fine. Any idea how to fix this or reset Open Brush on Pico? Thanks a lot! 🙏

    Is this the version of Open Brush from the Pico store?

    No, I downloaded it from GitHub https://github.com/icosa-foundation/open-brush/releases

    Oh, I figured it out! I deleted everything from the headset and installed an older version — and now it works!

    I downloaded version 2.12.0, but now when I draw, I can’t see my room. It only lets me paint in the default environments that were available in the very early versions of Open Brush.

    we don't support passthrough yet on the Pico I'm afraid

    But I was previously able to draw and see my real room, and when I drew outdoors, I could see the street. Now this option has disappeared. Has it disappeared only on Pico?

    I don't think passthrough ever worked on Pico. Is that correct @mikesky ?

    It never did sadly. My OpenXR branch should work, however

    Is it possible to access the Icosa gallery from open brush installed via the meta quest store?

    Thanks, that worked. I didn't realize the meta quest store had release channels

    Is it possible to create custom guides? I didn't see the feature in docs but figure i'd ask just incase I missed it.

    do you mean like custom shapes rather than the built in primitives? what shapes did you want to use?

    @Petra > Hi there, a question about the Animation Timeline feature. The links (specifically for Quest 2+) on this page give an error. https://docs.openbrush.app/alternate-and-experimental-builds/animation-timeline If I go to Github, here it also says something is expired. https://github.com/icosa-foundation/open-brush/actions/runs/15901008321/job/45100219769 . > I haven't used SideQuest or something at all so I have no idea what I should be doing to get this feature still, but am I right that it is not possible to download it at the moment? If it* is *possible, what should I do or what am I not seeing? > Isn't there a way to load it from inside of OpenBrush when I'm on the Quest 3 (via Labs or something)?

    yeah - those links expire if we haven't run a build in the last 30 days. i'll trigger a new one now

    This may be silly but I was wondering if I could import a 3d model and use that as a guide. Mainly it's how brush snaps and paints on top of guides. For me shaping is what I end up spending a lot of time on and was thinking this could speed things up for me.

    We don't have anything like that but there were some very experimental attempts towards that - but probably not finished enough to be worth trying. Out of curiousity - what kind of shapes were you planning to use? it would be useful to have a specific use case to think about.

    Not specific. Just a thought I had for improving my speed. Like grabbing some low poly 3d models placing them in my scene and painting over them sounded potentially quick.

    is there a way to see exact RBG values? I couldn't find a setting for it.
  • a

    11/07/2025, 10:33 PM
    rgb values of what?

    colors you've chosen in the color picker?
  • a

    11/07/2025, 10:34 PM
    We could add that in but not sure how useful it is. Colors are complex and rgb values aren't terribly portable from one app or platform to another.
  • a

    i guess the one place they would be useful would be to tell another open brush user so they could match the color when using the same brush. But beyond that - it's probably not as useful as you think
