UCameraComponent::AddOrUpdateBlendable

function Engine Blueprint Since unknown

#include "Camera/CameraComponent.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Adds a blendable object (implementing IBlendableInterface) to this camera's post-process settings, or updates its weight if it's already present.

Caveats & Gotchas

• Thin wrapper around FPostProcessSettings::AddBlendable — the blendable is added to this camera's own PostProcessSettings, not applied globally.
• Passing the same blendable object again updates its weight in place rather than adding a duplicate entry.
