This shader node setup provides a visual tool for checking physically based rendering (PBR) albedo values against real-world measured data. By connecting a base color texture and selecting a reference value from the included cheat sheet node, the material will output a blue emission if the color is too dark and a red emission if it is too bright.

The reference values are based on the Google Filament and DONTNOD PBR cheat sheets. These nodes help users maintain accurate material properties for proper lighting interactions in PBR workflows.
