This is not another “nice-to-have” utility. DrDebug is a custom-engineered, 6000+ line C++/Blueprint/Slate look-dev suite built to expose the mathematical ground truth of your pixels. Stop guessing through broken view modes, fake masks, or buried console variables.
This is the toolset you reach for when:
Your Albedo looks right in theory, but wrong in-engine.
Your Project doesn't have PBR Standards.
Your Project PBR Standards take time to set.
Your Reflections don’t add up.
Your Decals are fighting the scene.
Eye-adaptation and Exposure are lying to you.
Your Ray Tracing setup is acting suspicious.
Your team needs one shared debugging standard instead of ten different guesses.
The Arsenal: Do what Vanilla UE5 Cannot
▼ Material Debugging
Albedo Debug: True base color inspection, including metallic contribution and luminance-aware analysis.
Ambient Occlusion: Validate material AO, SSAO, mesh distance fields, and DFAO checks instantly.
Reflection Debug: Read metallic, roughness, and specular together in one mode with proper lighting context.
Decal Debug: Isolate true DBuffer data (since Unreal removed the decal mask buffer), plus tangent-space inspection.
▼ Exposure & Lighting
EV Debug: Accurate EV100, Lux, and NIT readings. Stop trusting your eyes and Unreal's HDR (Eye Adaptation EV Reader), read the absolute truth.
False Color: Similar to Using Davinci Resolve, but in UE5, Map finale image's exposure ranges to real-time, customizable heatmaps.
RGB Waveform & RGB Histogram: Native C++ built scopes, extremely performant. Treat your viewport like a professional color grading suite, not a black box.
PBR Checker: A floating reference chart that follows your camera and stays useful across multi-viewport workflows, with the option to stop it from following the camera.
Render Diagnostics: Pinpoint bottlenecks with TSR inspection, TRUE VRAM readouts, texture pool usage, and Nanite-focused troubleshooting, Trace & Profile Scene seamlessly.
RayTracing Debug: Investigate true ray-traced behavior when surface-cache assumptions stop being enough, read RT Roughness project settings on the go.
▼ Misc Debugging
World Normal: Clean visualization of surface direction and normal map blending, reacts to directional light angle to see if normals are inverted or broken.
Shader Complexity: Essential performance profiling, docked right where you need it.
Opacity: Isolate masked and translucent rendering issues fast with split-screen.
SSS Color: Dedicated visualization for Subsurface Scattering to perfectly tune foliage and characters with split-screen.
Built for Production Pipelines
This isn't a portfolio gimmick. It's engineered for studio-wide, Perforce-friendly workflows.
Shared Project Presets: Leads can establish a shared baseline for the whole team.
Local User Presets: Artists can work and debug locally without polluting the project.
Zero Footprint: 100% touch-free transient architecture. No dirty levels. No master material edits.
Who is this for?
Environment, Character, Technical artists, Look-dev artists, Lighting, and Material/Shader artists who want faster diagnosis and zero wasted iteration.
Why should my studio invest in DrDebug?
Because art departments deserve a tool that eases stress, saves time, and maintains visual consistency without the headache. DrDebug permanently eliminates the "guesswork loop", the endless cycle of guessing what a shader is doing, tweaking a value, waiting for compilation, and checking again.
By giving your artists immediate access to Live Viewport Telemetry, the Split-Screen Scalpel, the Decal Debugger, and accurate Normal and Reflection debuggers, you establish studio-wide standards visually. It pays for itself the very first time it saves a developer an evening of blind troubleshooting, easily saving days of work per milestone.
