Result of render_multipolygonz() seem unsolid

[nahardito]

I am interested to build building object using rayshader. However, the building's wall seem unsolid. I am using the latest version which is 0.35.1. Do I need to downgrade the package to have the solid wall result same as yours? If I need to do that, may I know how to downgrade the version?
