Ok I figured it out, loading screen mod is breaking these assets for me, causing only the pillars to load in-game. Disabling it makes them appear again, idk why

Ground level road renders fine? I don’t think there is a problem with pillars. I think it’s about software. Maybe some drivers are bad or I don’t know what else. Or some mod causes those issues. Assuming you said that my roads are not the only ones don’t work for you.

Is it possible to upload a version of one of these without the pillars?
