UE 5.6 Iterative Cooking Skips Blueprint Actors

Development Pipeline & Plugins
, ,
1

Blueprint actors with StaticMesh/SkeletalMesh components do not appear in the cooked build when using -iterativecooking.

The Blueprints and level are saved, but iterative cook seems to reuse stale cooked data. Removing -iterativecooking includes the actors correctly. Is this a known issue with Legacy Iterative Cooking?

Thanks.

Hi Simon,

The Legacy Iterative Cooking mode does have lots of issues in tracking references. We are not making fixes anymore as we concentrate on the new Incremental mode which is much more reliable. The mode is present in version 5.6 and can be used in the new Project Launcher (Modified & Dependencies) and or by adding -cookincremental as an argument for the cooking process. When using UAT, it becomes -additionalcookeroptions=“-cookincremental”.

Regards,

Martin
