@andybak I did manage to work it out. However I did find that when trying to use a transparent background some of the shaders don't seem to like it. I tried tweaking my configuration maybe I was doing something wrong but idk. Maybe it's an issue with the shaders or a limitation of THREE.js ?

I've kinda lost track of the whole pipeline you've got going here. Can you spell out to me in detail what's going on in this images?

andybak•4/30/25, 8:07 AM

"However I did find that when trying to use a transparent background" - I'm not clear on what exactly you mean here.

Same issue we had with Passthrough blend basically, i saw it too when trying to make an AR viewer for Icosa a couple years ago

andybak•4/30/25, 8:25 AM

but what's the image on the right?

andybak•4/30/25, 8:47 AM

Pretty sure I've viewed most brushes in AR mode on Icosa on the Quest.

andybak•4/30/25, 8:48 AM

@Hyper - remember we're mostly on UK time. If you want a realtime conversation then bear that in mind.

andybak•5/1/25, 1:49 PM

Yep - you were right. When I try the viewer with Open Brush stuff in AR mode I get the same. Our shaders don't work properly with AR passthrough.

@Hyper - they seem to work fine with other elements in the scene. It's just AR passthrough that doesn't work. Can you explain what you mean by " transparent background"? Transparent in relation to what? Are you overlaying a three.js on top of other elements in the page? Or are you overlaying various parts of a three.js scene?

Aandybak Yep - you were right. When I try the viewer with Open Brush stuff in AR mode I g...

HyperOP•5/1/25, 2:19 PM

Yes overlaying the three.js on top of other elements in the page, specifically a video feed from a camera. Setting the background to null in the scene initialization. Half the shaders don’t seem to handle the transparency properly in that situation.

HHyper Yes overlaying the three.js on top of other elements in the page, specifically a...

andybak•5/1/25, 2:20 PM

I hadn't spotted this because usually Open Brush scenes have a skybox that hides passthrough. We'll take a look but it might be a couple of weeks away.

HyperOP•5/1/25, 2:26 PM

That’s alright. I worked around it by having my friend change some of her models. Then it turned out the deadline has been extended a month so I thought I’d ask in the off chance the issue might be resolved and we could use her initial designs.

HHyper That’s alright. I worked around it by having my friend change some of her models...

andybak•5/1/25, 2:27 PM

It's something I want to fix pretty soon because it affects viewing in AR. But i'm away next week so I won't be able to take a look until the week after.

andybak•5/1/25, 2:28 PM

If you know anyone who's good with WebGL - we could use some help in that area!

HyperOP•5/1/25, 2:29 PM

Unfortunately I don’t. And I’m certainly no shader wizard or I would have tried to solve the issue myself

HyperOP•5/1/25, 2:33 PM

My expertise is in Unity, so C# and modeling, game design etc. Have only dabbled in JavaScript a bit.

Have done a handful of things with Unity webGL but not with webGL directly

andybak•5/1/25, 2:58 PM

You could probably do a Unity WebGL build of the sketch using the Open Brush Unity SDK

andybak•5/1/25, 2:58 PM

it would be a lot heavier than the native GLTF version however.

Hi guys, how do I import files into open brush?

PPAT Hi guys, how do I import files into open brush?

andybak•6/3/25, 12:36 PM

You're in the Icosa Gallery channel. Do you mean "how do i import from Icosa Galley into Open Brush" or something else?

PAT•6/3/25, 12:37 PM

Hello. Yes

andybak•6/3/25, 12:38 PM

We haven't released the full integration yet. Should be ready in the next few days.

andybak•6/3/25, 12:38 PM

Until then you can just manually download and copy into your Open Brush / Media Library folder?

Does open blocks have fonts?

PAT•6/3/25, 12:48 PM

Or is there anyway I could do on a windows pc and import into Open blocks library

andybak•6/3/25, 12:50 PM

sorry - those sound like 2 unrelated questions. i think i'm misunderstanding you?

andybak•6/3/25, 12:50 PM

what are you trying to do?

PAT•6/3/25, 12:51 PM

I have a project where I needed to create a model in VR. But instead of doing it in VR, is there anyway I could create 3D models on my desktop and import into open blocks vr.

andybak•6/3/25, 1:55 PM

We should probably move this discussion to #open-blocks-chat . Can you DM me an example model so I can try something? And are you using blocks via PCVR or standalone?

andybak•7/8/25, 6:29 PM

Yes. Very soon. I'm stomping the last few bugs as we speak.

andybak•7/8/25, 6:30 PM

grab the beta if you're feeling brave. the more people testing it, the better.

can you add a link to the beta? Is it on github?

Hey I am very new to this but I was looking at the gallery and just wanted to ask how the embeds work?

peter•7/10/25, 3:47 AM

As I saw a work I really liked but was surprised because the work was uploaded recently when it was made 5 years ago and the artist hasnt be active on anything for what seems like a year

andybak•7/10/25, 8:34 AM

I might be misunderstanding your first question as it seems unrelated to the second bit?

peter•7/10/25, 12:25 PM

Oh I guess they are unrelated excuse me

Ppeter Oh I guess they are unrelated excuse me

andybak•7/10/25, 2:14 PM

So, can you explain in more detail how you want to use embeds? Where do you want to embed a piece of work?

peter•7/10/25, 4:13 PM

Oh wait nvm I think I understand now it uses iframes

(also coming soon - export camera pose and sparse point clouds directly inside Open Brush ready for generating splats using any standard tool like PostShot, Brush or Lichtfeld Studio )

andybak•9/17/25, 4:38 PM

This will hopefully be a cool way to share complex Open Brush scenes in a much smaller (and less processor/GPU intensive) way.

andybak•10/8/25, 3:27 PM

Added support for .sog format compressed splats. This whole scene is only 16mb: https://icosa.gallery/view/ZTLkNjE82Ys

You'll be able to generate this from your Open Brush sketches which should allow viewing of scenes that would usually be too big for normal viewing.
