MipMapBias not working on mobile

Hey Guys, I am trying to change my mip map bias via code, with this line, it works fine on the mac, but it doesn’t work neither on Android nor iOS. Anyone has an idea ?

Thanks a lot for your time.

From the documentation (pay attention to the bold part it applies to android):

A positive bias makes a texture appear extra blurry, while a negative bias sharpens the texture. Note that using large negative bias can reduce performance, so it’s not recommended to use more than -0.5 negative bias. In most cases better sharpening of the texture can be achieved by using anisotropic filtering. Also note that mip map bias does not work with MaterialPropertyBlocks, and some platforms, e.g., OpenGL ES based do not support it without custom shaders.
