Some users may see a black floor in the VEXcode VR Playground. This display issue has two known causes, which vary depending on your device. To resolve the issue, find your device type in the sections below and follow the corresponding instructions.
Chromebooks and Android
If the VR Playground's floor is turning black on your Chromebook or Android device, this means that the Chrome web browser is using the Vulkan API to process VEXcode VR graphics.
We are aware of this issue and are actively looking into a solution.
Note: Because of this issue, the Fill area with color Block and pen.fill() command will not function.
A potential solution to this issue is to press the Playground Reset button. While this may reset the floor and resolve the issue on the next load, it is not guaranteed to work.
This will not work on the 123 Playspace Playground.
Windows and Mac
If the VR Playground's floor is turning black on your Windows or Mac device, that means that the Chrome web browser does not have graphics acceleration enabled.
VEXcode VR Playgrounds are 3D applications that require graphics processing to function. By default, your browser may not use your device's full graphics capabilities. Enabling graphics acceleration lets your browser use your device's graphics processing unit (GPU) for these tasks. This can improve the performance of the Playground.
Not having graphics acceleration enabled can also lead to a lower frame rate, incorrect sensor data from the VR Robot, or improper behaviors from the Pen tool.
