    Hello is it possible to do vertex displacement based on a texture using the shader graph ?

    If so, can you help me to do it ?

    I can easily do some vertex displacement using noise but I can't figure how to do it with a texture.

    Ok I just had to use "Sample Texture 2D LOD" instead of "Sample texture 2D".

    Weird , I thought LOD was only to gain control over mipmap. Do you know why this works and not the other?

    AFAIK at the vertex stage of a shader mip level is not chosen yet, so you have to specify it yourself.
