Packaging failed

Hi!

I’m trying to cook my project but I have errors like this:

UATHelper: Packaging (Android (ASTC)): LogCook: Error: Content is missing from cook. Source package referenced an object in target package but the target package was marked NeverCook or is not cookable for the target platform.

I already found some post about it but using “Validade Assets” are not working.

Did you check to see if the target package “M_Default” is marked as “never cook”?
Looks like you’re using a material from the interchange gltf pipeline. I don’t know why it would be marked as “never cook” but that’s where I’d start looking
