Models can be moved while selection tool is inactive

Imported models can be grabbed simply by intersecting. This makes it very difficult to keep them in place, which is a problem when they are major scene elements that everything else is relative to. Particularly when there's multiple brush strokes and images tied to a model. This behavior does not apply to brush strokes.
The grab action may be related to a right finger trigger press, as I usually notice it when scaling the scene....

4 Way Mirror has Copy/Paste Bug in the Official Beta

The plugin scripting bug appears in the official build and I think its connected to the mirror. Using the 4 way mirror, manually spin it, copy what is generated several times. You are no longer able to manipulate/interact with it. Once the entire sketch was deleted, you could no longer paint.

Not generating a bat file for 360

Created a sketch and filmed in The Scipting experimental build but get a blue screen when trying to generate a 360. I opened the official OB beta, refilmed and no bat file was generated. Resaved the sketch as a new sketch, reshot the video and the bat file was not generated a second time.

Snapshots only show up if you reboot the device

The snapshot folder is empty, it shows there is a new file eg the count has increased by one, but the file is not shown. If I connect it to SideQuest it is there, but on the device it self I can't view it.

Powershell commands in registry key?

Hey folks - we use and love Open Brush at the University of Minnesota - our IT Security flagged a potential issue though. I'm not a programmer; could you take a look at their message and let me know what you think? "Host is triggering alerts in Defender for suspicious process execution of powershell commands and suspicious powershell in registry. Upon investigation it appears that an application that was installed from Steam and is called TilBrush/OpenBrush. This program installation has stored...

official build doesn’t quit

Getting the circle of death on the app in Oculus. It won’t quit. Even when I restarted the oculus app, it was still cycling preventing me from opening other apps as well. It wasn’t showing in the task manager to do a hard quit.

The stereo-360 videos aren't really stereo

I'm working on an Unreal Engine project for VR that relies on some 360 stereo footage previously captured with Open Brush. However, to my dismay, I discovered that the videos produced by Open Brush have identical top/bottom frames! This can be easily verified in Photoshop by overlaying the halves of any frame. It doesn't provide a 3D view but rather just a 360 photosphere. The result in Unreal Engine is extremely disappointing. Upon closer examination of the generation process, I noticed that in the .usda file used by the batch process, there is this information: uniform token stereoRole = "mono" . I ran the batch for two modified .usda files (with parameters "left" and then "right" instead of "mono"), but once again, the frames came out identical (see the result in stereo-left-right.png). However, in the next test, I numerically modified the camera coordinates to shift it 64mm to the right, and I obtained identical top/bottom frames between them but noticeably different from the previous file. I manually combined the frames (taking the top from the initial file and the bottom from the one with the right-shifted camera), and I obtained a view that, at least when looking forward, is what I need (see the result in stereo-manual.png). Unfortunately, this cannot be a solution because when looking backward, the eyes receive views that are simply inverted, as if you were looking cross-eyed. Multiple captures should be taken, gradually rotating the left-right cameras around a fixed point and combining the central strips of the resulting images. At least this is the solution described by the creators of the stereo-panoramic plugin for Unreal, where the results are indeed 3D. https://www.unrealengine.com/en-US/tech-blog/capturing-stereoscopic-360-screenshots-videos-movies-unreal-engine-4...

Pico 4, Video recording is not working.

Video record function is not working in the latest update downloaded from Sidequest, gifs and pictures do work, but it fails to start capture with video. Also in the newest update sometimes it causes lag and strong visual artifacts when the camera tab is opened.

Screen is pink when playing scene "Main" in Unity and viewing a sketch?

This occurs regardless of what SDK mode is set in Config. At start, the sketch selection menu loads and pink screen occurs after selecting "View sketch." Is this a render pipeline issue?

Point of Origin Issues on Exported Models

Error Message still referencing Tilt Brush

Creating 360's and started a new one before the last was complete. Not sure if you wanted to change this or not due to branding.

3D Printing Brush Error

Official Beta: 3D printing brush on export (GLB) is showing pink in unity, brushes not combined and listed as: Hidden/Internal/ErrorShader as brush type. If I change the brush type to Brush/Diffuse/DoubleSided it shows properly. However, not all of the 3D printing Brush strokes are showing in Unity.
