The material in gltf file is described like this: "materials": [ { "name": "surface_style_43_默�_楼板", "pbrMetallicRoughness": { "baseColorFactor": [ 0.588, 0.588, 0.588, 1 ], "metallicFactor": 0, "roughnessFactor": 0.99 }, "emissiveFactor": [ 0, 0, 0 ], "alphaMode": "OPAQUE", "doubleSided": false } ], In the gltf view-tool,it appears "red"color ,but after converting it to b3dm,the color disappear. I hope you can give me some guides.Thank you very much.

Is your gltf file from an IFC file or are you just using the GLTFS2B3DM step?

Because the IFC2GLTFs step uses the "--materialsCommon" flag (now modified to "--unlit" flag) for obj2gltf which does not produce gltf files with PBR materials. I suggest you use this flag and run the converter again because it does not support PBR materials.
