Maintaining materials / colours when exporting .dgn to .ifc

Hi everyone,

I'm exporting a .dgn file as a .ifc file, but when I do I lose any assigned materials (regardless of if it is by level or by individual element). Not only that, but the .ifc file has all elements in red, regardless of the colour they were in the .dgn. I'm wondering if I can maintain the assigned materials through the mapping options when I export, but I'm not familiar with data groups or families, and my attempts at doing this have been unsuccessful. If I can't maintain materials, is it possible to control what colours elements are in the .ifc?

I'm currently using OpenBuildings Designer CONNECT Edition Update 8, Version

Any advice would be greatly appreciated!
