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 to change a static mesh's material in C++?

I have an Actor class with a SphereComponent and a StaticMeshComponent, and I wanted to change the Static Mesh's material when something overlaps with the SphereComponent. I don't have much experience with materials so I'm kinda stuck on this.

Simply SetMaterial:


Easiest way to get material is to make UMaterial* varables for each with UPROPERTY(EditAnywhere,Category=Something) and set them in editor, you can also GetMaterial to get current material of mesh

Alternativly you can make one material with parameters that changes it's apperence


Here is example i find to change material parameters in C++: https://answers.unrealengine.com/questions/4323/questionedit-material-parameters-c.html

I tried the SetMaterial approach and it didn't work, I think it might be my Constructor here. PointNotCaptured being the UMaterial variable I made.

 // Sets default values
      // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
     PrimaryActorTick.bCanEverTick = true;
     SphereComponent = CreateDefaultSubobject<USphereComponent>(TEXT("Root Component"));
     RootComponent = SphereComponent;
     StaticMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Point"));
     StaticMesh->SetMaterial(0, PointNotCaptured);

Wait nevermind, SetMaterial did work when I used it in a function. Though I am still confused why it didn't work in the constructor.

I was having the same problem, when I called SetMaterial in the constructor nothing would happen. I figured out setting the material directly on the static mesh and not the static mesh component worked...

 static ConstructorHelpers::FObjectFinder<UStaticMesh> plane_mesh(TEXT("StaticMesh'/Engine/BasicShapes/Plane.Plane'"));
 static ConstructorHelpers::FObjectFinder<UMaterial> plane_material(TEXT("Material'/Game/ClassicMansion/Materials/M_FlippedBorder.M_FlippedBorder'"));
 BorderMesh->GetStaticMesh()->SetMaterial(0, plane_material.Object);
