Two materials in curtain mullion

[Mike Sealander]

I want to model a curtain mullion with one material for the mullion body (behind the glass) and one material for the mullion cap. I think I'm out of luck. Any way to do this?

I don't believe you can do it in the same mullion profile family.
Is this just for visualization or are you looking to tag the material?
How about making the cap part of the curtain panel family?

I think I would put two curtain walls in the same place. One would have the mullions and panels. The other would be open panels and caps. Create the one CW, copy in place, isolate one CW - empty all panels and change the mullions to the caps with the proper offset.

Thank you for the replies. The reason was for visualization. As such I decided not to use two curtain walls, although the thought crossed my mind. If I render in Revit, I'll probably just switch materials between interior and exterior renderings. If I end up in Max, I'll probably change the material by face there.
I briefly tried to create a nested family mullion, but it doesn't work.

I have done that and added some parameters to control the caps extension over the panel reference lines and it works well. technically caps are not mullions and I am not sure why some people are trying to modeled them so, if just for presentation and design intent yes if not like for fabrication an detail drawing then your idea is the ideal for now until Autodesk come up with something genius

i forgot who did the webinare, but there was a tool out there that take your conceptual curtain wall (Glass and mullions and trims) and convert those into structural elements and families.
Basically it changes from a a wall with nested components to 1000+ individual pieces.
Not sure I like the idea, but they have a tool that will do it. Looked really slick. I just don't know what it does to your model performance.
