Package USD Stage into Project

Development Pipeline & Plugins

Hi, I am triing to package my Architecture Project in Unreal 5.5. Because the reimport function of FBX and GLTF seems to be completely broken with Blender Geo, i tried to use USD to import my scene. I activated the USD Plugin and load the USD in the USD Stager. Everything working good so far, even reimport. But when i try to package my Project, the USD is missing.

I tried to create a level Blueprint that opens the USD Stage with an external file, but seems like this is not packaging, too.

How can I Get my USD Stage in a packaged Project?

With a stage actor, all the USD is info is stored in a temporary fashion,

  • you could try to save the USD cache asset in your project and then package.
  • else you will need to import your stage actor so that you get proper UE assets, actors and component that you can then package into your application.

Can you give some details on what is failing when your try to reimport FBX and glTF?

Hi, here is an example video of the broken gltf support, fbx looks quite similar but destroys the model even more.

Parts are missing or have the wrong size/orientation

How can i save the USD cache for packaging? By using a level blueprint and loading it to a stage?

I did internal test on packaging your USD stage actor for cooked application.
You still cannot do it with an editor that comes from the launcher. You still need to rebuild the editor from source while enabling the FORCE_ANSI_ALLOCATOR=1, and then you have to package with the custom built editor.

ATM The simplest way would be to duplicate your project and import the USD stage actor into the content browser and scene just for the packaging.
