Sometimes I get a warning indicator that shows up over the center of a noodle connecting two nodes. What does this indicate and is there somewhere i can look to see what the warning is? This is happening mostly for connections between normal map pins.
You can click the connection that has the warning, it will tell you what’s going on. It typically only means something like “be careful here”. In this case it might be a colorspace conversion where one output is set to “Linear” and the input is “sRGB”
