how to export animation glb file?
Good day~ we want make a VR gallery app on headset, which can show 2D painting and 3D Vr painting. It is a platform for free. We want make the painting share more easy in such way. But when we try to make a damo, we find the glb file export from mulitbrush or openbrush is not animation. The painting is static.
Anyone can help me?

The animations in Open Brush are all in the shaders - you'll need to use the actual shaders. Is your VR gallery built in Unity or is it a javascript thing?
I want more people can enjoy this VR art. I hope it is easy share and show. So we just want upload the glb file to our host, which can export from openbrush.
Then everyone can load our app, type the gallery ID, they can see the VR drawing in our app.
But what we get is static VR drawing only.

There are two different to use our shaders:
1. Via Unity
2. Via javascript and three.js
So I was asking you whether you are a Unity-based app or a native web app?
I'm guessing Unity. Is that correct?
If so - you want to look at our Toolkit/SDK: https://docs.openbrush.app/user-guide/open-brush-unity-sdk
Open Brush Unity SDK
Using Open Brush with Unity
I hire programmers make this app for my company. Yes, he is use unity, I will share this document, I hope it is helpful for our project. Thank you so much.
Anyway, I like this VR art, And I want more people can enjoy it, but not just watch it from some video. It is very shock if you can walk in the painting.
Your programmer is welcome to join the Discord if they have any questions
@andybak Just as a follow up, I've exported the glb files from the Original Tiltbrush, I know .glb can contain animation and wanted to export the file WITH the "embers" brush for example. I've used Adobe Aero that displays .glb file in AR, will it be possible to get imbedded animation via Open Brush ?
Our animations aren't "animations" in the sense that glb means. We're using custom shaders to do animation. Glb animations are keyframed transforms (for the most part)
It's hard to even think about how to convert one to the other. You'd have to split each "ember" out to a separate mesh and generate keyframes for it. Not trivial...
We have versions of our custom shaders on two platforms at the moment: Unity and WebGL. I doubt using them with Aero would be possible without Adobe's help
What's the final output from Aero? A native app of some kind?
or does the viewer run in a browser?
Thanks for the quick reply. I think its a web app, heres the link :
https://adobeaero.app.link/lhFgAieiuwb
thats the activation image
I think it's a webapp
Needs an iphone though
That seems to just be a qr code. On Android it links to a Play Store download.
I think on iOS they might leverage the native USD viewer? I'm not seeing any clue that it ever takes you to a regular web view
Yeah, on an Iphone when you click the link it runs the webapp
can you send me the url for the webapp? I wonder if it's got apple-specific stuff in it
These run natively on the iPhone but needs an app install via some supported androids
so - sounds like it never generates a standard web page.
I use a glb export from Tilt Brush, which looks great - the link I sent activates on an iphone or with the app installed, the saved files is cloud based then called down by the link, dynamically loaded.
Back where I said:
What's the final output from Aero? A native app of some kind? or does the viewer run in a browser?The answer seems to be "a native app" or at the very least "some iOS specific feature" which means there's no way for our WebGL shaders to hook into it. I was wondering if you could take the Aero output and inject our stuff back in
I'm not sure, I had the feeling it is running a web based app via the Aero
Unless you can find a url where "view source" shows the actual content then probably not
OK, well thanks so much for having a look and being engaging 🙂
I'm so pleased to see this app still ahving a life, its great, The multiplayer option would be excelent, i see there is a paid version of that but a free one would be amazing. If I can help or test in anyway
Thanks. We're working on it!
