Graphics Test Settings component reference

Explore the settings you can use to customize the graphics tests in a scene. For more information, refer to Customize tests.

Property Description
Use HDR Generates images using high-definition rendering (HDR).
Use back buffer Captures images from the back buffer instead of a render texture.
Target width Sets the width of the captured image in pixels.
Target height Sets the height of the captured image in pixels.
Comparison settings Sets the sensitivity of the comparison between the test image and the reference image.

Comparison settings

Property Description
Per Pixel Correctness Threshold Makes the test fail if the perceptual difference between two pixels is greater than this value. Unity uses the DeltaE formula to measure the perceptual difference between two colors.
Per Pixel Gamma Threshold Makes the test fail if the RGB gamma difference between two pixels is greater than this value.
Per Pixel Alpha Threshold Makes the test fail if the alpha difference between two pixels is greater than this value.
Average Correctness Threshold Makes the test fail if the average difference between the images is greater than this value.
Incorrect Pixels Threshold Makes the test fail if the ratio of incorrect pixels to correct pixels is greater than this value.
Active Image Tests Sets which method Unity uses to calculate the difference between the test image and the reference image. The options are:
  • None: Doesn't compare the images.
  • Everything: Uses all the methods.
  • Average Delta E: Uses the perceptual difference.
  • Incorrect Pixels Count: Uses the ratio of incorrect pixels to correct pixels.
  • RMSE: Uses the root mean square error.
Active Pixel Tests Sets which method Unity uses to calculate the difference between individual pixels in the test image and the reference image. The options are:
  • None: Doesn't compare pixels.
  • Everything: Uses all the methods.
  • Delta E: Uses the perceptual difference.
  • Delta Gamma: Uses the RGB gamma difference.
  • Delta Alpha: Uses the alpha difference.
