# Unreal Materials Skill Material development using Unreal Engine's Material Editor. ## Overview This skill provides capabilities for creating materials in Unreal Engine, including PBR workflows, material instances, and custom shader development. ## Capabilities ### Material Creation - Build PBR materials - Configure material domains - Handle blend modes - Manage material properties ### Material Instances - Create instance hierarchies - Expose parameters - Handle static switches - Manage instance overrides ### Material Functions - Create reusable functions - Build material layers - Handle function inputs - Manage function libraries ### Advanced Techniques - World position offset - Pixel depth offset - Custom UV manipulation - Subsurface scattering ## Prerequisites - Unreal Engine 5.0+ - Material Editor knowledge ## Usage Patterns ### Material Parameter Setup ``` 1. Create Material Parameter Collection 2. Define scalar/vector parameters 3. Reference in materials 4. Update from Blueprint/C++ ``` ### Material Instance Dynamic ```cpp UMaterialInstanceDynamic* DynMat = UMaterialInstanceDynamic::Create(BaseMaterial, this); DynMat->SetScalarParameterValue(FName("Damage"), DamageAmount); MeshComponent->SetMaterial(0, DynMat); ``` ### Material Layers ``` 1. Create Material Layer asset 2. Define layer parameters 3. Create Material Layer Blend 4. Configure blending 5. Use in Material ``` ## Best Practices 1. Use material instances for variants 2. Create material f...
