Hello, There are a few types of foliage that cause the editor to crash when I move them or manipulate them. All the other foliage types I have work perfectly, I just have the issue with a few types. When I select the problem types and try to move them the editor freezes then crashes after a few seconds. The foliage files are there and do reside in explorer. Thanks for any help you can provide!

Hi oxygencube,

- Does this occur in a clean, blank project with no additional content or is it limited to one project?
- What steps have you taken to reproduce this on your end?
- Can you post your crash logs and callstack here? The logs can be found at \Unreal Projects\PROJECTNAME\saved\logs.
- What foliage assets specifically are causing this to occur?

Hi ,

**Does this occur in a clean, blank project with no additional content or is it limited to one project?**  
This seems to occur only on one project.

**What steps have you taken to reproduce this on your end?**  
I load my map and try to move certain foliage types using the selection tool or indirectly using the sculpt tool.

**Can you post your crash logs and callstack here?**

**What foliage assets specifically are causing this to occur?**

Where are the positions of the foliage instances stored? In the type or the map? It looks like there is a miscommunication of data somewhere.

Is the asset a custom asset or one you got from the learn tab/marketplace?

It is a custom asset. I have tried replacing it with a different asset and the problem persists. The asset is working well as a foliage asset in other levels. I have a firm belief that there is a problem with the array or location data.

The second crash (sculpting landscape) is a known issue, UE-28926. I’m focusing more on the foliage selection, which I have not been able to reproduce. Do you see this occur with basic assets, such as the Editor cube?

Everything is working correct with 98% of our other assets so I would imagine that this would work correct with a basic asset as well. I have tried removing all instances of that foliage asset and repopulating them with the proc. foliage tool and I still get a crash when I try to move them individually. If I place them using the basic foliage painter then I am able to move them.

I have tried creating a new foliage type with a different custom mesh and still get the crash.

I created a foliage type with the engine cube and was able to move the instance.

Some meshes I am able to move one at a time but if I select multiple and try to move them I crash.

I spawned new foliage using same types, assets, and spawner on new map and am able to move single and multiple instances, but still get a crash when trying to sculpt terrain.

Can you explain to me where the position for foliage instances is stored? The level file? The foliage type?

As I looked into the known bug: UE-28926 I think they are related. If sculpting the terrain with foliage causes crashes… maybe it is trying to move the instances and throwing an error. Thus if I try to move them by hand it throws the same error.

Try generating a handful of different types of foliage using proc. foliage spawner or then move a bunch of them around.

Hi oxygencube,

Thank you for the additional information. This was reproduced internally and we have entered a bug report, UE-29242, to be assessed by the development staff.
