Topo Subregion appears transparent

[steve]

All in A360: 

1. I created 2 models of homes, call them A and B.   
2. I created a topo base model in "TOPO" model.   
3. I linked TOPO individually back into A and B using insert/link Revit to locate the homes.   
4. linked A and B back into TOPO. I turned OFF A&B's topo.   see visibility settings here from TOPO (this one is viz of A did same with viz for B)... https://drive.google.com/file/d/1cQ8_tu6rlPvCAFvMVSLZEuWRQ3ECuIva/view?usp=drivesdk
5. I created subregions of asphalt for road and driveway in TOPO
6. topo-subregion of only the drivweay of B shows grass material thru it.    I have deleted and re-made it, no help.    It also renders as grass in lumion
7. see all here... https://drive.google.com/file/d/19tasNJEnCVww5rifa0H5v1nezBfQr_6h/view?usp=drivesdk
8. to be double shure, I unchecked all topo categories in the main link and the subcategory link called "5"(whatever that is)   see linked jpg called VIZ2
9. WHAT DO YOU THINK IS WRONG... IDEAS HOW TO FIX?

Set the Topo Link  to "Attachment" (not "Overlay").

Ignore that last post.  

Can you post your files (A, B and Topo)?

Can i make you a collaborator?   I don't want to post entire projects to a public forum.
