Walls completely facing the sun appears dark


Weird thing happening where a wall that’s completely facing the sun can be dark (as if it was in the shadow). On the other hand, a wall that’s partially facing the sun is lit as expected. Any suggestions on this?

Are you able to reproduce this in a Sandcastle example that you can share?

Just tested some more and found that it only happens on the tileset and not on a custom gltf model. I can send you a private message with the tileset.
