How to do realistic ceiling tiles without a surface pattern?

[Anonymous]

Can anyone point me in the right direction of how to do this? 

I am uploading my models into Lumion to render and surface patterns arent visible in Lumion so i need too somehow make a realistic ceiling grid where you can see both the metal grid and the plasterboard ceiling so i can assign materials to both.

To be honest I am very dissapointed that revit doesnt have this feature allready.

Thank-you

As others have said, the best/fastest way to handle that is using a material that renders the way you want.

If you really need to model the actual ceiling, a curtain system or structural beam system is the way to go. For the curtain system, you'd need to create a mullion family with the profile of your grid and a panel family with the material of the tiles. If you use a beam system, just create a structural framing family with the profile of your grid, then locate your ceiling.

In the screencast below, I just used OOTB families but you can see how it works. For the framing system I used a T shape and rotated it 180 deg. When you create your own framing family and the profile is oriented correctly, you won't have to rotate it.
