Terraforming polygons disappear when moving away the camera

Hi, Since SU6 I’m having an issue with terraforming polygons. From close
distance it works ok but if you start to move away the camera it starts to
disappear. Here are some images and a video showing it. Is this a bug? Near:


Yes, it is a big problem, and it becomes very complex to use terraforming
correctly since the last update. Adding vegetation is now also very difficult,
as it does not appear on the polygon. It seems to me there is a refresh
problem, and i really hope it will be fixed soon.

Thanks for confirming. It’s really annoying indeed, hope they’ll fix it soon
too. It seems that it only affects devmode, package works ok, but it’s really
difficult to lay polygons correctly if you can’t see the results.
