Blender + Virtual Desktop passthrough on Quest 3 is something else. Quick tutorial.

#tutorial 1. Enable the passthrough environment in virtual desktop. 2. Under streaming tab, set your passthrough color. 3. Launch SteamVR 4. Enable built in VR addon in blender 5. In solid view in blender, change background setting to viewport and change the color to whatever you set your passthrough color to. 6. Launch VR session under VR tab 7. To fix being able to see through your blender view on virtual screen, split view vertically, slide the window with the green background over, and set your new viewport back to default settings. If you change your initial viewport you launched vr from, you will break the passthrough, so just keep that viewport as small as possible.
