D5 does not reflect toposolids cut from Revit

I’m having trouble with how D5 does not reflect the topo solids cut through from my Revit model. When trying to set a material for the place where it should be it says “the material of the model cannot be reused” but it detects the topo solid being cut. But It reflected when I tried it with other rendering app.

Is there anything I can do about this?

Hi @allyy

Sorry for the inconvenience. May I know the version of your Revit and the Revit LiveSync plugin? In some instances, complex material assignments from Revit may not sync properly or display correctly in D5. Thanks
