This is an update to Leo Mystic Magic's 18 hole golf course.
The original set had culling issues with the renderer which caused the assets to flicker on and off as you zoomed in or navigated around your city.

The issue was that the pivot point / origin of the original assets was placed at the far end instead of the center.
Cities Skylines uses the pivot / origin location to determine object culling by the renderer. In other words, when the origin goes off screen, the object stops rendering. With assets this large, and the pivot at one end, it is easy for the pivot to leave the camera view frustum while the rest of the object is still on screen. Thus, the object disappears as it is culled while still in camera view.

By placing the pivot in the center of the object, we increase the probability of the pivot being in camera view by double.
Because these objects are so large, it is still possible to get the object to drop out when it reaches the edge of the camera view, but the drop out is dramatically reduced from the original version.

All credit for this set goes to Leo Mystic Magic, and you should contribute to his patreon if you like this set.
The only reason I'm updating is that many users have commented on this issue for some time without resolution.

Apologies to Leo Mystic Magic if I step on his toes.
