# Debug IDs of Runtime Layers
Easily display the data stored within your data layers
## From your surface material - MFC\_PositionToUV
You can find a texture array of numbers named T\_NumberArray inside Shader World content folder, under Material/Numbers.\
Using world position XY coordinates, as UV, and your runtime layer ID as index inside the texture array, you can display the IDs information stored within your layers.
