Maquette is a VR prototyping tool for Steam VR compatible devices, currently in beta. Maquette enables users to quickly communicate spatial prototypes in virtual reality. It was built from the ground up as a generalized prototyping tool intended to empower anyone to create fully immersive content in VR without the need of software outside the VR headset. Maquette includes a set of tools for importing, creating, and composing content in 3D space, and maquettes can be exported for use outside the tool. Our development priorities are guided by users' needs, so we want your feedback!
