Heyo, I'm not really sure how to explain this properly but I'll try my best lol
Basically, the structure "cementworks_conveyorhall" will de-render if you look at it from a specific angle, the angle is quite hard to explain.
You stand near the rear of the building and look off to the side, the building will de-render at a pretty specific angle (but it should still be visible as the building is still within the view of the player, allowing the player to see through where the building is. I will provide some screenshots here
Here is an image of how the building should look :
Here is an image of what happens when you trigger this specific "de-render angle"
I apologise for my horrible explanation, hopefully you understand what I'm saying lol, thanks <3
