Different colors -> when is used color from ifc file

[JanoSlivka]

Hello,

I have question about load color of element from ifc file. Both ifc files have defined same color for element.

This ifc file load color from file. roof_color.zip

This ifc file use default color. roof_default_color.zip

Why?

Thanks for help.

I have not been able to figure it out, but loading this file [1] in Blender with the IfcOpenShell plugin also results in geometry with the default color applied. So I am thinking it's an IfcOpenShell issue.

One difference I see in the files is that [1] uses IfcMaterialList to define the materials, and [2] uses IfcMaterialLayerSetUsage.

[1] roof_color.zip [2] roof_default_color.zip
