Unity 5.6 Upgrade Canvas UI Changes
I noticed this message appear after upgrading on all of my Overlay Canvases in my game.
Unity shader channels Normal and Tangent are most often used with lighting, which an Overlay canvas does not support. It's likely these channels are not needed.
I understand what the message is saying, and I've turned off all of the elements (selected Nothing -- see screenshot) and tested my game and don't see any issues, but I'm curious if anyone can tell me where I may find more docs on these? What are TexCoord1, TexCoord2, & TexCoord3? Any reason why would one be on by default?
EDIT I realize now that the TexCoord* fields are most likely from a gradient shader/material I've created. Thing is, I can select Nothing and my gradients still work fine. Though perhaps this is due to the fact that I'm in a 2D Canvas with Screen Space - Overlay.
