Landscape collision and selection problems
I've been running into some pretty major, blocking problems when using the terrain system.
If I add a component, then it gets added without any collision. Physics-enabled objects fall through it. Worse, all the components adjacent to it also get their collision removed. This results in an effect where if I delete a patch in the landscape and then re-add it, then I lose collision on all nine components.
Anyone have any idea what might be going on here and how I can re-enable collision for everything?
I've also noticed that I'm able to get the selection tool into a state where I'm not able to deselect or do operations on a number of components. If I have some selected, and then go into the paint tool, or back into Place Mode, and then pop back into the selection tool, then they will be permanently selected. Additionally they won't be sculptable. This puts me into a state where I need to delete the components completely and start again.
Hi, I tried to repro your case, but could not succeed in current version. It seems like updating nearby collision component has some problems, so it lose collision component.
What is your current version for UE4? Could you share your level to figure out what is the cause?
For the quick fix, you can try "RecreateLandscapeCollision" console command. It recreate collisions of all landscape components.
Selection problem also seems to be related to collision problem. It seems that it is not sculptable or selectable, because it loses its collision component.
I would appreciate if you can share your contents to repro the problems.

Yeah Hi, I ran into the exact same problem. Im using ue4.13 to make an underwater scene, and while there isn't much inside it at the moment I've been trying to fix the landscape collision. When I first created the landscape the collision was working, but after I added a multiple-terrain-material to it, it vanished. Then the problem with the paint landscape tool started taking effect after a few saves.(Hasnt caused me top lose work yet, but thats cause if I click in and out of the window a few time it seems to jar it out of the bug)
