Threshold editor LAB not showing / tracking pixels

Postby 166inter » Sat Oct 13, 2018 3:08 pm

Hello, I have been using the threshold editor before without and recently, I cannot see any tracked pixels in the editor, except for when I am in grayscale. Does anyone have an idea why?

Um, have you tried changing the color tracking bounds? They have to be adjusted given the image and lighting.

Hello, yes, no matter what bounds I am using for the thresholds, it is always black.

Can you post the source image from the frame buffer? If you right click on the image and save it I can then try with my viewer.
