Import .uassets from a folder

I saw this topic answered but I wanted to document that the answer doesn’t work for me.

I tried dragging and dropping the .uasset file as suggested from a project A into another project B. When I reload Project B, the folder is present in the content menu, but none of the assets are available.

I can’t migrate the content folder for Project A because the project will not open on my machine. It was a folder transported from a different machine.

Hi PrintmakerJMLee,

If the project they are being taken from is a newer project these will not open as they were created with a newer build. Do you know the project version the files were created with?

Also, is there a reason the project A will not open on your machine? The project folders can be me moved from computer to computer so long as their is a version of the engine that can run it.

Thank you!

Tim

Thanks for responding, Tim.

I have engines 4.6, 4.5 and 4.4 installed on the current machine. None will open Project A. Project A was definitely built before the release of 4.6.

When I click on Project A, or try to load it in the engine I get the following message:

"The following modules are missing or built with a different engine version:

UE4Editor-LandscapeMountains.dll

UE4Editor-VehicleGame.dll

Would you like to rebuild them now?"

I click “yes” and it returns an error: “LandscapeMountains could not be compiled. Try rebuilding from source manually”

I have taken a look at some of the files with Visual Studio, but my knowledge of C++ is limited. I was able to get “VehicleGame.dll” to drop from the original message by updating Project A to 4.6. But I always hit the “LandscapeMountains” error.

What files are you trying to grab from Landscape Mountains or Vehicle Game? I can test these on my end as well.

I recall seeing a message like this before when I tried just dragging some content to another project folder. If I remember correctly I believe my error was that I was not keeping the same folder structure so it was not happy about that.

My suggestions (if you’ve not already tried) are:

  • try moving the content, but keeping the same folder path for anything after Content forward.

Ie. If you grab something from landscape mountains / Content / Materials / Textures

You’ll need to place it in your new project in New Project / Content / Materials / Textures

This is what happens when using the “migrate” option as well.

  • Are you able to grab the projects from the launcher and re-download? Whether your account is active or expired as long as you had access to them at one point you will be able to grab them now.

Let me know! :slight_smile:

Tim,

I believe you’ve come to a similar conclusion as I have. The file structure on the original machine is different than what I am currently working with, so the DLLs (if they exist) aren’t looking in the right spots.

The original Project A used both VehicleGame and LandscapeMountains. It was kind of a demo of the engine. I can still run the executable file and see both levels in action, but the project file gives me the errors I mentioned.

I just grabbed the original unaltered folder and dropped it into a “Projects” folder with “VehicleGame” 4.6 and “LandscapeMountains” 4.5-4.6.

ProjectA was built in 4.4.3

  1. When I click on it now, it says “Project modules are missing or out of date. Would you like to recompile them?”
  2. Click Yes
  3. Error “Game code couldn’t be compiled. Continue trying to start anyway?”
  4. Click Yes
  5. Message “The game module ‘LandscapeMountains’ could not be found. Please ensure that this module exists and that it is compiled.”

Tim,

Any update? I tried the options above and haven’t gotten any farther along.

I’ve installed 4.4 and the 4.5/4.6 versions of LandscapeMountains to the drive in the same location as ProjectA. I’ve seen it an error that says the Map was built in a newer version of Unreal Engine. That can’t be possible, because I’m using 4.6 and the original was built in 4.4
