I am getting inconsistent results from the File Output Node when using .png.
Here is a render (a Fresnel output) that is manually saved out. It matches how it appears in the image viewer. BW, 8bit .png:
Now, here’s the same thing outputted through a File Output node set on BW, 8bit, .png:
These are the exact same settings, but the version that came from the File Output node is darkened.
If the file output node is set on BW and 16bit, then it works correct. But then the file is 4x the size for no reason. 8bit ought to be sufficient.
Anyone know what could be going on? Is this just a bug, or am I not understanding something? (2.93).
