求助:用Composure打包出来运行不了，有大佬见过吗

I ran into this and it wasn’t a crash—just a black output. The root cause in my case was “Cook maps only”: with that enabled, the cooker only follows hard references serialized in the map. Many Composure materials live under the plugin content, and if they’re only default values on a component (not explicitly overridden in the level), those references don’t get serialized → they never get cooked → black screen.

Fixes (pick one or combine):

  1. Packaging settings
  • Project Settings → Packaging
    • Enable Include plugin content in packaged build (if available).
    • Add to Directories to Always Cook (adjust to your actual paths):
      • /Engine/Plugins/Composure/Content
      • or /Plugins/Composure/Content
  1. Asset Manager (robust)
  • Create a Primary Asset Label (e.g., Cook_Composure)
  • Set Cook Rule = Always Cook, enable Cook recursively
  • Add the Composure content directories to that label.
  1. Make hard references
  • Duplicate the Composure base materials into your project as Material Instances and explicitly assign them on your Composure actors/elements in the level (so they’re different from CDO defaults). This forces a hard reference the cooker can see.
  1. Soft-reference bootstrap (last resort)
  • In a persistent BP (e.g., GameInstance/Level BP), keep a Soft Object Reference array of the needed materials/MIs/RTs and call Load Asset on BeginPlay.

Quick sanity check

  • Temporarily disable “Cook maps only” and package—if the black screen disappears, you’re definitely missing cooked assets.
  • Use Reference Viewer from your map to verify those materials are actually reachable.
