Hey @barbrian0723

are you using the same UE version?

You can try this:

  • Copy the new project
  • Delete everything except CONFIG, CONTENT, *.uproject file
  • Copy the old map into the same folder inside the new project
    – e.g. the map is inside Content / MyOldProject / Maps then you create the folder MyOldProject inside your new project and a folder called Maps inside the MyOldProject folder, so it looks like this
Content
     New Project
          Blueprints
          Maps
          Materials
     Old Project
          Maps
  • Copy the map / level
  • Start the new project

not the same version
old is 5.3
new is 5.4

let me try what you are suggeting

4

only thing i can find related to the map is map.umap and map_builtdata.uasset files

5

Hey @barbrian0723

then try

map.umap

6

i copied the files in a new folder in the content folder of the new project
the file is lying there but the editor is not picking it up
picking the rest up
picking map_builtdata.uasset up
but not picking up map2.umap

Hey @barbrian0723

the name and the folders have to keep their names. So map.umap has to stay map.umap and not map2.umap.

didnt change file names. i am beginning to think it is because of the version difference

Hey @barbrian0723

Migrating did not work? You could try upgrading the project and then migrate. Open the *.uproject file with notepad or a similar program and edit the version number. Then start the project and try again.

lol . what?? this deserves a 10x “heart” as opposed to the conventional like
did not know that hack is possible

seems part of the problem is plugins. once i have enabled the plugins again from old project to new project the old map now is available and visible in the new project

Hey @barbrian0723

could bei possible that there are assets in this map from a plugin making the map only visible when using that plugin.

map landscape material or lighting is still wrong

not sure why that would be

Hey @barbrian0723

what did you do to open the map? Are you in the old project? Are you in the new project and copied the map by youself or did you use Migrate?

If you copied the map by yourself you will also have to copy the missing materials.

material is there so it is not that
seems layer info is missing in new project and must be rebuilt
might be that the migration failed when crossing from 5.3 to 5.4
