PBRValidator
An Unreal Engine 5.7 C++ editor plugin that provides a real-time PBR texture validation overlay, ensure that the BaseColor and Roughness maps in your materials comply with industry standards.
Features
- BaseColor / Albedo validation — Detects albedo values outside the physically valid range (too dark or too bright)
- Metallic reflectance validation — Checks metallic surface reflectance against 60–100% or 70–100% thresholds
- Roughness validation — Identifies roughness values outside the expected range
- Split-screen slider — Compare validated and original scene side-by-side in viewport
- Distance culling — Limit validation to objects within a configurable max distance
- Animated warning pattern — Optional animated overlay on invalid regions for easier spotting
