Pixel Inspector

PixelInspector.png

The Pixel Inspector tool is a Developer Tool that will allow you to diagnose the pixels that make up the colors in your scene. If you want to know why a pixel is producing an unexpected color (or maybe what Material input is driving a pixel's color), you can use the Pixel Inspector's Inspect Mode to output information that is driving the pixel's visual result.

Using the Pixel Inspector

To enable and use the Pixel Inspector:

  1. From the Main Editor Window go to the Window menu option under Developer Tools and select Pixel Inspector.
