Description

Blueprint function library exposing material and Material Parameter Collection operations: reading/writing scalar and vector parameters on an MPC, and creating dynamic material instances.

Caveats & Gotchas

• All Set/Get parameter functions operate on a Material Parameter Collection asset, not on a specific material instance — changes are global to every material referencing that collection.
• Setting a parameter on an MPC via this library only affects the current world's collection instance; it is not automatically replicated to clients in multiplayer.
• CreateDynamicMaterialInstance is the more common entry point for per-object material tweaks; the Set/Get parameter functions here are specifically for MPCs, a different mechanism.

Example

Update an MPC scalar parameter at runtime C++

UKismetMaterialLibrary::SetScalarParameterValue(this, DayNightCollection, TEXT("TimeOfDay"), 0.5f);

public	function	UKismetMaterialLibrary::CreateDynamicMaterialInstance	Creates a new Material Instance Dynamic (MID) from a parent material, allowing its parameters to be changed per-object at runtime.
public	function	UKismetMaterialLibrary::GetScalarParameterValue	Reads the current value of a scalar (float) parameter from a Material Parameter Collection instance.
public	function	UKismetMaterialLibrary::GetVectorParameterValue	Reads the current value of a vector (FLinearColor) parameter from a Material Parameter Collection instance.
public	function	UKismetMaterialLibrary::SetScalarParameterValue	Sets a scalar (float) parameter value on the current world's instance of a Material Parameter Collection.
public	function	UKismetMaterialLibrary::SetVectorParameterValue	Sets a vector (color) parameter value on the current world's instance of a Material Parameter Collection.
