Apply a "chalk effect" on a texture

Hello everybody,

Here are two screenshots from my project, first one is a “static” menu where I created the texture in photoshop with a kind of chalk effect on the static text.

Second is the same font than in first one but with dynamic text, so no more premade chalk effect from photoshop: my question is if you could think of way to produce a similar chalk effect with babylonjs ?
I am a sorcerer’s apprentice… I managed to do something on the wooden table below with bumptexture after doing some random tests with the texture app materialize, but my knowledge stops here, so any advice would be appreciated :o)

This looks like you can play with texture transparency. Try to bake the chalk effect texture to your diffuse alpha and use

myMaterial.diffuseTexture.hasAlpha = true;
