Blueprint Nativization disabled during "Cook Content for Windows"

When Cooking Content for Windows via its corresponding menu option with Blueprint Nativization enabled, the Log displays a warning:

BuildCookRun.DoBuildCookRun: WARNING: Project is configured for Blueprint nativization, but the conversion flag (-nativizeAssets) was omitted from the command line. No nativized assets have been built as a result.

But when I package my project, it uses the -nativizeAssets flag during cooking! I don’t think that this is intended behaviour. If I want to cook my content, I want to nativize Blueprints as well!

TriNityGER,

  • Could you please upload the full error output log?
  • Please also include screenshots of how your project is set up to package.
  • Does this happen in a newly created project?
  • Did this happen in 4.14 for you?

Looking forward to hearing back from you, thanks!

Hi. I also experience the same problem. It is reproducible always, even on tutorial projects.

The issue is simple:
When “Cook Content for Windows” is selected FMainFrameActionCallbacks::CookContent() function is called.
This function does not check PackagingSettings->BlueprintNativizationMethod and does not add “-nativizeAssets” option.
I don’t know if this is a mistake or by design…

“-nativizeAssets” option is added only in function FMainFrameActionCallbacks::PackageProject().

The warning is valid because we’re currently not nativizing during cooking however, we are going to enter a bug for this issue. The content will be cooked but it will not be nativized while using the ‘cooking content for Windows’. However, the blueprint nativization will cook when you package your project.

UE-42087 is the issue we’ve entered in .

I hope this helps, thanks!

Thanks for the reply. Can you make the issue public on issues.unrealengine.com?

Unfortunately not, as the ticket contains sensitive information that cannot be made public.

Can you at least provide current status information about the ticket? Can we expect a fix in 4.16?

Look for it to be resolved in 4.16. Let me know if you still run into the same issue after 4.16 is released and I’ll be glad to take another look.

Now, it is 4.16.0,but it still miss -nativizeAssets when I use Cook Content for Windows, and I checked My project setting → Blueprint Nativization Method is Exclusive.

Hello,

The nativization issue specifically has been entered as [UE-49544][1]. It should become public once it’s been reviewed.

Thanks!
