Two World Labs case pages describe game prototypes built on Marble splats. VIVERSE used a five-step flow (generate or select a splat in Marble, import into PlayCanvas, add colliders/triggers/lighting, optimise for browser and mobile, publish). Of three demos only Clockwork Conspiracy was newly generated, from a quoted text prompt. Gaussian Mansion (Unreal Engine 5 rail shooter) used Marble PLY exports stitched in Marble Studio and imported with a 3D Gaussians plugin, and names transparency, material and artifact problems. The only quantity is one developer's "under an hour" quote; neither page reports counts of levels, iterations or ratings.

Curator qualifications: World Labs case pages: VIVERSE five-step Marble to PlayCanvas flow; only one of three demos newly generated from a text prompt; Gaussian Mansion stitched Marble PLY exports in Unreal.
