Sublevel

A child level streamed in/out of a persistent level. Used for open-world streaming and modular maps.

CreateDynamicMaterialInstance — create runtime modifiable material

UPrimitiveComponent method. Store result in variable and reuse. Create once in BeginPlay.

FMod — floating-point modulo (remainder)

FMod — floating point modulus remainder

SetSkeletalMesh — change skeletal mesh on mesh component

UE5 uses SetSkeletalMeshAsset, not SetSkeletalMesh.

PlayMontage — play an AnimMontage on a SkeletalMeshComponent

Call on the SkeletalMeshComponent. Get it via GetMesh() on Character. Returns montage length. Exec out is 'then'.

CreateDynamicMaterialInstance — create a runtime-editable material copy

Must call this before SetScalarParameterValue/SetVectorParameterValue. Store the result in a variable for reuse.

SetMaterial — change material on mesh component at index

SpawnSystemAtLocation — spawn a Niagara/Cascade particle system

UNiagaraFunctionLibrary::SpawnSystemAtLocation. bAutoDestroy=true for fire-and-forget. Use SpawnSystemAttached to attach to a component.

ComposeRotators — add two rotators together
