Tiled Landscape Resample

Hello,

Is there a way to resample landscape tiles?
When I try to do so like we do with single landscapes the editor crashes.

-\Bump/-

Show what exactly causes the crash.

Here’s a couple landscape tiles using world composition.

Crash once I try to resample.

I don’t know what’s causing it of course.

Might be related to the fact that in WorldComp, the engine uses a single landscape proxy with multiple landscapes (or vice-versa, not in front of my editor at the moment), whereas in a Landscape tool scenario there is one landscape proxy per landscape model. Have you tried to go into the individual landscape sub-level (you can open them in the editor just like any other level) and resample in there?

Thanks for the suggestion. I just gave it a try but it still crash that way too.

There might be someone who knows a solution?

hello, I’m using UE4 25 and have same problem like you.

i’m was editing sub level,
migration to empty new project,
change Engine Scalability to low,
remove material landscape

my landscape component size is
section size= 63x63
section per component = 2x2
-number of component = 4x4
-overal res = 505x505
-total component = 16

and what i want is

section size= 127x127
section per component = 2x2
-number of component = 4x4
-overal res = 1,017x1,017
-total component = 16

is there solution for this issue or everyone have tips to resample without crash?

The original question is from 2016. But the answer is still the same.

You have to open each indivudual level and resample there.

i have tried it, but still crashes even when I open individual level.
do have any other suggestions?

Disable world composition in the persistent. Try the individual level again?

I did it, but it’s still crash.
maybe it could be that my PC can’t handle the process

Thank you very much for helping Sir.

To debug the error further you would need to install the debug symbols.
