IFC Materials

[Nivas83]

Hello,

I Converted IFC to XKT by using the convert2xkt js function. for each object, I have a material type (Glass, Concrete, and Wood) in the IFC file, But I didn't get material data in the xkt file. where I can get the material information in the xkt file?

Even These Material information are not available in the property set.

Thanks.
