How to use the new interchange pipeline to import meshes at runtime, packaged builds?

Bencsizy · November 24, 2022, 12:39am

Hi everyone. I would like to use the new interchange pipeline plugin to import meshes at runtime in shipping builds, but I could not find any documentations or resources so far on the topic. I have tried it and made it to work in the editor, but in a packaged build, it is simply crashing, so i guess I may be missing something. Any help is appreciated. Thank you

For non CAD

you can use asset import task, that should use the default interchange pipeline

else you can use the interchange code

you have two functions one to import assets and one to import scene. They are not using the same pipelines, so you can either let the “override pipelines” empty and it will take default pipelines for assets or scene. Or you can force custom pipeline stack

For CAD file import you should do something like:

Thank you for your reply, I tried these, both import scene and import asset, but none of them works in a packaged game. They do work in the editor however. I am getting these error messages when trying it in a packaged build:

Checking with dev.
Does that works if you enable datasmith interchange plugin and rebuild?

Bencsizy · November 24, 2022, 8:28pm

I have enabled all of the datasmith and interchange plugins. I am unable to package the app with it. This is the error I get:

UATHelper: Packaging (Windows): Unable to instantiate module 'InterchangeFbxParser': InterchangeFbxParser module can be build only on editor or program target.

UE_FlavienP · November 25, 2022, 9:13am

For your UE version, do you build from source or get version from launcher?

In your Import Scene function do you override pipelines or not?

Bencsizy · November 25, 2022, 11:41am

I got the version from the launcher.
I don’t override the pipelines.

Bencsizy · January 22, 2023, 8:49pm

When trying to package a shipping build, I get this error message. Is it expected?

Hi had the same error with 5.1.1.

Any idea how to resolve it?

Bencsizy · February 7, 2023, 8:16pm

Could you help us out, please?

Michael_page · February 10, 2023, 4:22pm

This error appear only when Datasmith Interchange is activated. When I desactive it, the code compile correctly.

UE_FlavienP · March 6, 2023, 5:23pm

If you build in development it should work.
This is fixed for 5.2.

mozg4d · March 20, 2023, 1:13pm

ue 5.2 (compiled from source) “datasmith importer” plugin enabled, cannot package (shipping and development, empty project)(

if plugin disabled - packaged ok.

This might be somehow linked to Holo lens platform. I tried to disable it and failed)

mozg4d · March 27, 2023, 10:04am

New, clean project; shipping; UE5.2 preview 1. Can’t package with “datasmith runtime” enabled(

ERROR: Non-editor build cannot depend on non-redistributable modules. … depends on ‘ProfileVisualizer’.

If packaging in development:
error LNK2001: unresolved external symbol __std_find_trivial_4

mozg4d · March 27, 2023, 1:52pm

Managed to package (only “development”) by disabling “geometry tools” plugin and all it’s dependents and it does import when I launch from editor, but “fatal error” at runtime(
tried both “automated” true and false

Tried Datasmith (*.glb), but it fails to generate distance fields so no Lumen and probably no Nanite(

look what I found)):

mozg4d · March 30, 2023, 1:46pm

minimal blueprint for both importing options:

works perfectly fine (including distance field generation; 5.2 preview 1) in editor and in “standalone game” launched from editor, but if packaged (shipping / development / debug, both import options) - fatal error(

*disable “Datasmith runtime” plugin for “shipping” packaging

UE_FlavienP · March 31, 2023, 11:49am

I will check for the disable “Datasmith Runtime” plugin

For your Error: can you try to add /interchange/ to the folder to be cooked

mozg4d · April 3, 2023, 12:10pm

unfortunately still fatal error either on “get asset tools” or on “create source data”.

Maybe because I cannot enable “datasmith interchange” as:
ERROR: Non-editor build cannot depend on non-redistributable modules. …exe depends on ‘SkeletalMeshUtilitiesCommon’, ‘ProfileVisualizer’

Minimal project with level blueprint attached
MyProject2.rar (34.9 KB)

If anyone managed to make interchange pipeline work in shipping build, sample minimal project will be very much welcome))

Bencsizy · April 3, 2023, 12:20pm

Any chance that this issue will be fixed by the release of UE5.2? We would like to provide Datasmith directlink and the interchange pipeline importing too for our users.

UE_FlavienP · April 3, 2023, 1:18pm

I have so crash on 5.2 Preview1, that are different from your issue. And no crash on the 5.2 I build from source. When I have some time I will do more investigation.
