Mip Level Feature ES2....limits for mobile

Working on a mobile game.
So i just discovered the button that gives me the mobile stats. Of course when I click it on I get a WHOLE bunch of errors on my landscapes and other materials about them
Mip Level Feature ES2

Easy enough to find that it is because vertex texture sampling is not supported well by mobile devices…
Is there a way to keep my materials and textures but change the sampling?

I’m completely new to materials and such and dont know exactly what it means when it says that, let alone how to modify it
