I’m using the most basic material where a value set at one connected to Base Colour. The scene itself is empty except for a directional light set at default values. I’m not sure why there’s a glow around each letter? The same material is set at Front, Back and Extrude.
Found the reason why. The directional light you add in the scene makes a massive difference. The material used for the text is reflecting the light. I suppose there are two ways to deal with it, either adjust the material itself to be less reflective or make decrease the directional light intensity if the other elements in your scene don’t depend on it too much.
