The unity canvus will issue the following warning
Shader channels Normal and Tangent are most often used with lighting, which an Overlay an Overlay canvas does not support. Its likely these channels are not needed
This warning can be removed in this way.
However, when you play unity, this setting will be restored and this warning will appear again.
The issue of settings being restored may be similar to this issue.
However, it has not been fixed
I don’t know what this setup does in the first place.
To me it is just garbage that gives offensive warnings.
Now, what can we do to avoid this unpleasant and meaningless warning?
The version of unity used is 2021.3.4f1
