UE 5.6 - USD Import through Interchange doesn't allow a selected Parent Material

Development Pipeline & Plugins

Hello

I’m importing a usd asset with textures and materials into Unreal via the Interchange Framework. The materials have been defined with a USDPreviewShader and eveything comes in correctly and hooks the textures up to the default shader.

I would however like to create Material Instance and define a Parent Material. This appears to work with FBX imports but with USD these options appear to be overlooked and whatever I define it still loads the default UsdPreviewSurface Material from the Engine folders.

Might i be missing something, or Is this a limitation of a USD import currently? And if so, are there plans to implement this down the line?

Thanks!

You can overwrite the default Master Materials used by the USD importer in the corresponding project settings section here.

That would change for all subsequent import.

If a finer approach is needed then you should try and use an interchange pipeline to override some of the master materials during the import process.
