AI Playground doesn't currently support multiple parallel generations. There is instead a logged error message: "Already processing a request. Please wait." However, that message isn't surfaced in the spatial experience. It appears the primary reason this wasn't supported is because the `Snap3DInteractable` prefab was sharing a material. This caused the preview thumbnail of one instance to replicate across all instances that hadn't finished 3D generation. I was able to accidentally trigger this by generating from Gemini and the Snap3D Example pane at the same time. I have corrected this behavior and added the ability to generate multiple 3D objects in parallel. I will submit a PR and link it to this issue.
