Hi .
Ue5.0.3
I get this error Landscape physical material need to be rebuilt(1024objects).

I can’t fix it. I’ve already tried a lot of things.
Rebuild doesn’t help either. I couldn’t find anything on the internet.
Can someone help please?

Hello michaelmagic97, than you for posting your question.

Would you mind elaborating on what you rebuilt exactly? I was a little confused, I apologize. Generally when I need to rebuild landscape-related materials, I would go to Build>Build All Landscape. I noticed that once I paint (even a little more) I would have to rebuild again.

I look forward to your reply.

Thank you for your reply. I don’t know why but when I click to Build>Build All Landscape, it doesn’t do anything and it shows me the map check. And it does not perform the Build itself.

I have fixed the issue by changing engine code
follow is the solution

Lnadscape.cpp

you will find the code below

LastBakedTextureMaterialGuid = BakedTextureMaterialGuid;
LastSavedPhysicalMaterialHash = PhysicalMaterialHash;

this two valuable only set in giseditor, not with editor
