Brightness value ~

Is it possible to get an overall brightness value? Like, the sum of all the pixels’ alpha values? I’d like to send osc that’s based on how bright my output is, something like a visual equivalent to audio react :confused:

Yup, you can use something like an Analyze TOP to get the average pixel value, then you can use a TOP To CHOP to turn that texture into channel values that you put into a little CHOP network to do some math to turn the separate RGB channels into a brightness value like the first answer to this post:

Thanks!
