Self texture for OSM and

Hello everyone, I am learning right now cesium futures and trying to make a cut out zone from OSM buildings with cesium polygon raster overlay.
It works well, but at the moment I add mine texture to the buildings in the texture slot - the polygon is not working anymore and it keeps spawning buildings in that zone.
Is there any solution for this?
Hope for your advice.

I’m not quite sure what you mean by “I add mine texture to the buildings in the texture slot.” Can you show us exactly what you’re doing and what’s happening?

Hello Kevin, thank you for your answer!

After deep learning I found that I need to add the layers with all needed parameters to my base material to make this all futures to work.
I Took it from an example in tutorial and now all works fine.
