TextMeshPro blurry (using SDFAA)

Here is how it looks like:

 

This is because the wrong shader is used. Make sure that once of the Signed Distance Field shaders is assigned to the material used by this font asset.

I suspect that you might have first create a font asset using one of the bitmap modes and then switched to one of the SDF modes after. As such, the material was first assigned a bitmap shader.

 

That was it, Thanks!
