audioreactivity in blender

Hi i tried to follow this tutorial https://www.youtube.com/watch?v=0yA49cwE_V4- its just a simple tutorial about making an audioreactive orb, but instead i tried to make a bird audioreactive- its feathers were made of petal brush. However, when i subdivided petal brush, there were too many faces, and the fps is too slow. I was wondering if it would be more advisable to try making a different brush audioreactive? such as one of the hull brushes? thank you!

How to run Open Brush properly on Vive Focus 3?

Hello 🙂 I work for a small theater where we would like to give VR painting workshops on our in-house VR headsets, which are all Vive Focus 3. I tried downloading the Open Brush OpenXR Quest file from itch.io and installing it on the headset via USB. When I search for the Open Brush app in the VR library, it comes up as a 2D app and doesnt run properly (a 2D screen pops up, then it immediately crashes). How do I install Open Brush so that it works? Or is it not compatible with Vive Focus 3? Thanks for your help!...

Can not select items when copied and rebrushed

Beta prerelease/Steam. When you copy and paste part of your piece and rebrush, you can not always grab the rebrushed part after to move it. It's stuck in the original position. Happened with both original and experimental brushes.

Mylar Brush Export Issues

Imported an FBX of my model in Unity direct and the mylar brush does not keep the same shape as it does in Open Brush (loses the taper of the brush stroke). That should say Unity up top. Can't edit the title.

Tilt Brush Toolkit File Content Summary

Looking at this, mostly in the context of gltf handling.
Currently, there's no real good place to keep these kinds of things without them getting scattered Likely will have a number of follow up questions, observations or other notes, so this seems like as good a place as any to put this for now. Document has an overview of what's in each file in this part of the program...

glTF import (to Blender) issue 1

@andybak You were asking if that was normals issue when importing OB-exported glb. Well, looks there's bump map missing. I suppose it is Roughness channel that is missing in this glb. It seems that such map should work through normal map node, but it doesn't do that as expected i guess. Here i'm sharing recent video of OB-Blender work-flow with glb file. Here by the end i even achieved quite nice result by switching to Harsh Blend in Material Properties Settings. Oh, and i finally made this normal map of Icing brush working - not exactly it should, but i like the direction.., it was always missing or just didn't affect anything. What you see here are official TB brushes. I'm also sharing in this folder images of how glb stroke looks in blender when just imported and the screenshot of shader nodes, that Blender builds. https://drive.google.com/file/d/1zvOd8E9dnkIeuQAWuD5oAHqE6k4tzX4x/view?usp=sharing...

Paint strokes shifting on guides

There has been an issue with the brush strokes moving away from the guides on each brush stroke, it eventually is off the guide itself the more brush strokes you do. It’s almost as if each paint stroke on the guide becomes like a new “guide” increasing the distance of the stroke from the original one. Any way that can be tweaked a bit? It’s a noticeable bug since TB.

use 3d reference model as exactly-positioned reference scene

Is there a way to import a reference model not as a moveable/scalable reference but as a fixed "scene" to sketch over? Alternatively, when adding a reference 3d model to a sketch, have its position and scale set from the original model's origin/scale? My current workflow is using unity realtimeCSG to rough out a scene/collision mesh, export the model as FBX, import into OpenBrush, and then try to roughly match the scale. Then I add brush embellishment, export the sketch from OpenBrush back into unity, and manually re-align the brush strokes to my original CSG mesh. I figure I can probably edit the sketch file with the reference mesh in it to exactly position/scale it, but wondering if there's an easier way....

Displaying in screen view, but not headset?

1.0.173 Displaying in screen view but not displaying in rift headset? Initially tried to do this from the gitcode, and same problem, thought it might have been a mistake in the unity setup. Maybe a setting?
Then I tried to download the main github code version same result. Attempted to download the rift_experimental version (1,0.173 again, and did the same thing on the desktop. Oculus simply shows oculus home in all instances...

Geometry Mask for scrollable Animation timeline

Is it possible to create a mask for geometry? I have a slider that represents an animation timeline and I want only part of the slider to be visible at once, the part in a container. (Similar to html's overflow hidden). I'm new to Unity so any help would be awesome :)...

Editable Models

Was this polyhydra or an attempt at control point manipulation or something else? Does it actually modify models, or did I just misname it? If it does, how does that work?

No functionality?

Hi so I'm not even sure where to start, I simply cannot boot OpenBrush anymore with any functionality. It will open but this is all I will see. I have tried uninstalling and reinstalling through both steam and oculus with no luck. I've tried the current, previous and beta versions which all look the same as well as uninstalling and reinstalling steam vr and liv. I've verified the integrity of the files as well with no success. Any clue?

Buttons switched sides (unity)

Hi all, I was making changes in some panels and now when I run openbrush the buttons switched sides, even though controllers are being recognised in the correct side (the menu is on the left). So for example, when I want to paint I have to press the left index but the paint still flows from the right. I went back to a previous version where everything was working, but it is also broken....

GLB Models Import Problems.

Using the oculus store version. Attempting to import a glb/gltf file created exported from adobe stager. When attempting to import the model, it appears to import and the outline is visible when select all is used. The image is viewable and readable in paint3d (windows), 3dviewer and is visible in explorer via 3dViewer.
I uploaded the piece to a site, minted it and redownloaded it. Attempted to import that way and received an "invalid file format" response and an X through the model....
