Hello all, just busted out my ML2 and had issues with just seeing a cube. The Hub tracks the camera but when I hit play in unity I get nothing. When viewing the camera view in Game Mode it is a black screen. When I go into scene view and look at the moving camera gizmo the little box showing what the camera sees can see the red cube.

Thanks in advance

Your Unity version will need to be updated to 2022.2.0b4 or higher.

Multiple instances of adb are executed — Unity runs an instance for "Build & Run," the ML Hub runs one for the App Simulator, and it's possible you may be running an adb server from the command line without realizing it. In normal circumstances, the versions in Unity and the ML Hub do not cause issues, but you should check if there's a stray process running elsewhere.

We have some documentation for setting Permissions. This will explain the steps that may be missed.

Hello and thank you, sorry I was running 2022.2.04b9. Dumb question but how do I check if I have multiple adbs running?

I don't have Windows to test, but I expect it to be something like this:


On a *NIX-like platform, such as Linux or MacOS, it would be something like:

ps aux | grep adb
