How to transfer assets between projects

I wanted to know how we can transfer assets between projects in rocket such as particle effects and blueprints.

You can either copy paste the assets to another project through explorer or you can choose Migrate… (Recommended) to copy assets to another project.

Hi RyanJon,
When we have used these instructions, we often end up with blueprints with broken links, materials that no longer reference their correct texture samples, static mesh’s without materials applied etc. Do you know how to solve this or shuold I open a new UDN ticket?

Thanks for your help

If you make sure that all of your assets are within a single folder ( have as many subfolders as you want)

and then you migrate the entire folder

does that work for you?

Here’s what works for me:

  • Make sure the Object is in a folder and all dependencies are in the same or a subfolder
  • Right-Click → Migrate
  • Make sure that all dependencies are listed in the upcoming dialouge
  • Choose the Content folder of your project → Important: Don’t choose a subfolder! If you choose a subfolder dependencies will be broken!

This would be better as a comment than a new answer.

Hello,

I have had the issue and after some time testing with trial and error i figured out how to do it and what makes things mess up.

You need to make sure when using the ‘explorer’ method, (which is copying within windows explorer from content to content), that the address line for the assets are the same as the target location.

So for example, if i was wanting to copy assets from Project A to Project B, lets say in this case it was a particle system. I would need the particle system and all the assets it uses, such as materials etc, all within one folder. Then i would need this folder to be in the root of our ‘Content’ in Project A. Now keep in mind Project A is the source. The reason we are moving the folder of assets to the root of ‘Content’ is to ensure the address line is correct for the assets. So if particle system was trying to reference a material, it would have no trouble finding it.

So once we have our folder in place and ready to copy. that is just what we do. Copy the folder and files it contains to Project B. Now we need to make sure to copy the folder and files it contains to the root of Project B’s ‘Content’ folder. This is very important. By doing this the files will have the same address line as the source project. So now once you open Project B you should have working copied assets. You can now move the assets within the editor and organise as you please. Make sure you save everything.

Now what we have done.
We have taken the ‘folder’, which was here;
/Project A/Game/Content/folder

and we have moved ‘folder’, here;
/Project B/Game/Content/
so now we have the address line as /Project B/Game/Content/folder

What is important here is that we have maintained address lines for assets to reference. As we have copied through explorer, it would not act the same as migration, which fixes this for us.

If the source address is /Content/Particles/folder
and you copy to /Content/stuff/
the assets wont work

So make sure the target has the same order in sub folder.

Hope this helps, sorry for the long message, but its worth it. If i do not make sense, please help refine the solution.

Just one question; What if i don’t even have the .uproject file with me and just the assets, how do i make it work or how do i make sure my dependencies are all correct or how do i know which references are being used in what folders (as i don’t know coz there’s no .uproject file by which i can open the project and check or migrate)
