Why Unity thinks that animator parameter is being used by the Blending Tree?

Why unity is showing this msg box when i try to delete the FOV parameter. I’m not able to find this parameter in any of these Blending Tree as can be seen in the Image neither can i find this parameter in any of the script. I must be missing something?

Hi @Shock-Wav3,

It’s probably just not updated correctly in the editor on the blend animation under “Speed” Multiplier.
Other warning we cannot see on your screens since they are on different Animations / transitions

Also your blend tree is expecting a parameter.
