In Unreal Engine 5.7, materials aren’t just static visuals. They can be fully dynamic and controlled in real time using Blueprints. Building on basic texture swapping, this tutorial walks you through creating a fully adjustable material system where you can control:
• Brightness
• Contrast
• Tint
• Normal map intensity
All of these will be exposed as parameters that you can tweak live using a Material Instance or drive through Blueprints.
