GetPixels Alpha Values

Hey, I’m using GetPixels to read the camera output into a ARGB32 texture, and i want to process the pixels depending on their alpha values.

I was thinking the background would have an alpha value of 0 while the rest of the scene (just a simple plane for testing) would have an alpha value of 1.

But it turns out the background has an alpha value of 0.01960784

and the scene an alpha value of 0.4980392

why is that? can i change these values?

Ok sry the answer was simple:

the default diffuse material’s color alpha is 0.4980392
while the defaults camera background color.a = 0.01960784
