glTF

glTF (.glb, .gltf) is a common 3D format for rendering, games, the web and AR. It has shapes and materials but no BIM meaning.

Export

File › glTF (.glb) for Blender writes every element as a mesh named with its CreaBIM id, with its material's colour, roughness, metallic and opacity (glass stays see-through). It opens in Blender, three.js viewers, Unreal, Unity and most 3D tools. For the way back from Blender, see Blender.

Materials from glTF

Materials › Import materials…, opening or dropping a .gltf or .glb file adds its materials to the project (base colour, roughness and metallic).
