Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Component not showing up in PIE mode

Hello. I construct a UStaticMesh component programmatically inside my component and attach it to mine; it shows up right away. However, when I go to PIE mode inside the editor, it does not show up. If i click on any of the component settings in details panel while in PIE mode, it magically shows up and stays visible.

Regarding my slave static mesh component I do just this:

 UStaticMeshComponent* StaticMeshComponent = ConstructObject<UStaticMeshComponent>(UStaticMeshComponent::StaticClass(), GetOwner(), NAME_None, RF_Transient);

 StaticMeshComponent->AttachTo(this);
 StaticMeshComponent->RegisterComponent();
 StaticMeshComponent->SetStaticMesh(StaticMesh);
 StaticMeshComponent->SetVisibility(true);
 StaticMeshComponent->SetRelativeTransform(FTransform(TransformMatrix));


Any ideas why this is happening?

If anyone is interested, this issue was related to components (newly created components from serialization just for PIE mode) not having their render state created. There's probably a better way, but detecting PIE mode in OnRegister and manually calling RecreateRenderState_Concurrent solved the problem. Thanks.

could you expand a bit how you solved that?
