Shapelab VR is described as 'Shapelab is a VR-only 3D design application primarily for organic modeling. The robust dual-engine voxel sketching and polygon sculpting toolsets allow for creating high-quality props, characters, and concepts for applications, games, and virtual worlds' and is a 3D Modeler in the photos & graphics category. There are four alternatives to Shapelab VR for Windows, Steam, Meta Quest and HTC Vive. The best Shapelab VR alternative is Kodon. It's not free, so if you're looking for a free alternative, you could try Blocks. Other great apps like Shapelab VR are MasterpieceVR and Quill by Story Studio.
Shapelab is actively developed and available on more platforms, while Kodon has been abandoned for several years.
