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"

How do I change a root component's mobility back to Movable?

Here is what I did:

  1. Created an empty pawn, which inherits a root component.

  2. Added a couple of static meshes (spheres, to be precise), which become children of the root component.

  3. Accidentally changed one of the sphere's mobility to Static, which made the root component Static (yes I understand why it does that, no need to explain).

  4. Changed the mesh's mobility back to Movable, but the root component stays Static.

  5. Now I can't figure out how to ever make that root component Movable again, since its properties are greyed out.

Thanks for any help!

Product Version: UE 4.13

Hi Grey Ninja,

I attempted to reproduce this but I couldn't get your results. On step 5, the properties of the DefaultSceneRoot are not grayed out and I'm able to change the Mobility back to Movable.

Have you tried to test this in a clean blank project or is it only happening in your personal project?

I apologize, I forgot that my Step 1 above is not exactly correct. It was actually a new class derived from an empty pawn. The constructor of the new class has the following line:

RootComponent = CreateDefaultSubobject(TEXT("RootComponent"));

This root component has greyed-out properties, but I don't understand why.

For me, a StaticMeshComponent that is part of a ChildBlueprint doesn't have the option to set the Mobility. The only option is Movable. How are you setting this in 4.13? Have you upgraded your project from an older version?
