Has anyone else had a problem building for quest 2 where when they export the APK using the guide on

Has anyone else had a problem building for quest 2 where when they export the APK using the guide on the openbrush GitHub for quest 2 that the build is a folder rather than an APK file?

Does anyone know how to make the APK from the folder?

I tried installing Android studio.

I was wondering if maybe it's because I didn't approve the connection request inside the headset before building?

Generally I've not had a problem with making Android builds the regulsr way

The build should have an APK inside it... what do you see there?

I'm seeing basically what looks like an unzipped APK

You build via the GUI Tilt->Build (or something like that)? And the output was in ../builds/Release_OpenBrush_FromGui../builds/Release_OpenBrush_FromGui or something (i forgot the exact details but it should be something similar)?

Yep

chardOP•11/29/21, 4:29 PM

Sorry I didn't see any documentation for this part

Cchard Yep

mikeage•11/29/21, 4:30 PM

that is... strange. It'd take me 2 hours to reproduce because I recently wiped my local Library folder, but it should have some JSONs (unneeded) and an APK. Are the files you're seeing in the root, or a subdirectory? Can you paste a screenshot or directory listing?

Yeah don't worry about reproducing it, I'll be back in an hour and I'll share add much as I can

mikeage•11/29/21, 4:32 PM

ok, great! We'll continue later.

This is the only documentation we really have https://github.com/icosa-gallery/open-brush#building-your-app-for-oculus-quest

What do you mean by "export the APK using the guide"? What's the export?

chardOP•11/29/21, 4:40 PM

That's the one, yeah sorry I just meant do a build rather than export

chardOP•11/29/21, 4:40 PM

Following those exact steps there

that's weird

chardOP•11/29/21, 5:26 PM

I'll try again with the quest set up properly

mikeage•11/29/21, 5:32 PM

ok... it looks like you actually opened the APK! I don't know enough about windows to know if that's standard or something you installed... but if you go up one directory, is com.Icosa.OpenBrush.apk actually a directory or is it a file that you can open like a directory? Maybe from the command line... what does a simple dirdir show?

chardOP•11/29/21, 5:51 PM

yeah sorry it's just showing up as a folder

chardOP•11/29/21, 5:52 PM

But I'm also getting some build errors mainly relating to google drive, which I got stuck in the process of setting up

ah google is telling me I can just zip it up and rename it to an apk

Cchard ah google is telling me I can just zip it up and rename it to an apk

mikeage•11/29/21, 6:10 PM

I have to admit, I haven't seen this failure.... I wonder if the build was interrupted before the end? Happy to hear how it works after the zip.

chardOP•11/29/21, 6:15 PM

yeah it's likely, could've failed because it has an error and then doesn't package it as the final step

mikeage•11/29/21, 6:17 PM

that seems likely. Let's see if it gets better once the other errors are fixed.

chardOP•11/29/21, 6:22 PM

Yeah the apk doesn't run, it must've aborted during build

chardOP•11/29/21, 6:22 PM

Any chance I can just disable the online componants?

Cchard Any chance I can just disable the online componants?

mikeage•11/29/21, 6:24 PM

Probably, although I'm not positive that's your only issue. Our official builds come with keys for sketchfab and google, but when we test PRs and forks, they're not there (straight stock from git) and those compilations are also working, so I think there might be something else as well. That said, I'm not sure what it is -- I'm not really an expert in Unity. Maybe we should move this from #archived-support-and-bugs to #archived-dev-getting-started (although honestly, we mostly have the same people everywhere

)

Andy, any ideas?

chardOP•11/29/21, 6:35 PM

Would you recommend just pulling the from https://github.com/icosa-gallery/open-brush instead?
I was hoping to just get a quest app running with my custom brush shaders, maybe a few nicities from the experimental versions

Yes, just start from there, get it compiled, and then start your work

I think it's the last error preventing the build though?

andybak•11/29/21, 7:44 PM

btw that PR is currently buggy. I pushed a fix this morning that broke scene merging completely. will fix tomorrow

andybak•11/29/21, 7:45 PM

Can't help much on the build stuff as I never build locally. I rely on @mikeage 's nice CI cloud build

s_haha_n•12/2/21, 10:09 PM

is there a way to adjust for the brightness in recordings? so it's the same as snapshots?

mikesky•12/2/21, 10:10 PM

hmmm, this looks like a colour space issue possibly?

s_haha_n•12/2/21, 10:17 PM

in the past i've exported to unity and recorded that way, but always wondered if this issue could be solved, i think it "started" when i used quest+link and set the visual quality settings to max and then the video recorder just doesn't capture at that setting? also wondering if it's a quest+link only thing?

s_haha_n•12/2/21, 10:18 PM

i'm still messing with my config but not sure if some setting here could help? *just noticed the video resolution not supported. can those 3d error panels that fall on startup be viewed elsewhere?

AncientWorlds•12/3/21, 2:51 AM

I think you hit some limits with the quest itself, since it's got a limited processor on-board,
so presumably affects video recording. I can't remember if it records paths on the quest although I assume it does (it's a .usd file)
(I usually use desktop, so my memory of the interface specifics is a bit vague),
If so, there's a command line tool to record at higher resolution from the computer itself that can rerun the path and re-output the video file.
Not sure about the lighting mismatch.
You should be able to brighten it by moving the slider on the right side of the lighting panel up a ways, if the option is available.
Wouldn't solve the mismatch, but as a temporary measure should give your scenes more light in general, resulting in lighter colors on the output

Hello, I begin with OB and Unity. In Unity, I have imported Open Brush Unity SDK and after the fbx done in VR in OB, the problem is my model in the scene appears totally white. May I have to do other things to get alive my model ?

Try using the glb/gltf instead of the fbx. See https://docs.openbrush.app/user-guide/open-brush-unity-sdk

Gildas•12/3/21, 6:28 PM

thanks for your answer, I import the glb in Unity project folder, but it's forbidden to put it in the hierarchy

Gildas•12/3/21, 6:39 PM

sorry, before this, I have an error when I import sdk : "Multiple precompiled assemblies with the same name Newtonsoft.Json.dll included or the current platform. Only one assembly with the same name is allowed per platform. (C:/Users/Gildas/Documents/Unity/ago9/Library/PackageCache/com.unity.nuget.newtonsoft-json@2.0.0/Runtime/Newtonsoft.Json.dll)" so I close unity project and reopen it, and this error disapear, then i import the model

Gildas•12/3/21, 7:15 PM

not easy, i arrived by import comet.png which exist in fbx export, and reassign texture in unity.

So nothing will work when there's a red error in the console. We need to solve that first.

makes a lot of sense. ive heard of using the paths before might try that. and yeah makes sense its the questlink setup i remember using a vive a while ago and didn't have this problem

AncientWorlds•12/4/21, 12:47 PM

Video export using the usd and bat files is described here.
https://docs.openbrush.app/user-guide/exporting-videos
Camera paths are automatically generated when filming, at least on the pc side (need to open my quest again and look)
The video pathing feature, where available, can also be set up directly.
Takes a bit of practice to use it well, but it's a really nice system that's quite powerful.
Extremely useful for scenes that are too large to easily walk through or reach different angles.

If I have a horse model in unity, and I want the horse to ‘transform’ into a cube, how do I do this? I think I’ve seen stuff about this in machine learning art? Where you take 2 forms and the algorithm finds the midpoints between them? How could I do this in playmaker please? Thank you!!

Ozymandias•12/5/21, 3:47 PM

sorry have seen this sort of art around here so was wondering if anyone had suggestions re what to google! Thanks a lot!
