IFC Visual Export - Not working?

[JEdu_GM02]

Hi all!

I have some problems when exporting to IFC from Civil 3D, I have correctly assigned the colors to each of the elements within the program.

But when exporting the model, everything goes totally black.

Any idea on why this might be happening?

Thanks in advance.

The question would be, does Civil 3D export color to IFC? 

i.e. inspect the IFC file and search for color...

Should be... right? Tried to export using elements generated in Civil 3D.

The problem is that this workflow starts from importing a previous IFC, could that be the issue? Or could it be the elements are multi-view block references?

Thanks in advance.
