I'm working with a model with many materials on it. Previously, any time I would click on the Image Texture node in the node editor, it would send the image from that node into the Image Editor automatically. This is what I assume to be the intended behavior, and was very useful in going back and forth throughout my different materials and making changes to them. It has since stopped doing that, and while i can still change the texture shown in the Image Editor manually, it's definitely not as quick or ideal as having it update to match what I'm working on in the node editor. I don't recall having changed any settings, so I'm wondering what caused this change in behavior.
My first thought was to check the image pin setting, but it was off. Tried turning it on, then off, but still no dice. Also seems to persist through completely restarting the program.
I have also found that if I create an entirely new material with an image texture node, I can get the Image Editor to update... once, for that material. Then it stops working again. Any help or pointers appreciated.
