Material HDRP changing texture scale at runtime doesn't work

    Hello guys, i have some simple code there :

    Code (CSharp):
    1.  
    2.         MeshRenderer.sharedMaterial.mainTextureScale = new Vector2(1, textureRepeat);

    My texture is set as : Wrap Mode : Repeat.

    My code works well with the shader unlit/Texture but with HDRP/Lit changing the scale does nothing.

    I'm missing something with HDRP ?

    Thanks !

    The "_MainTex" is no longer used in the HDRP lit shader so that shortcut won't work. I'm not sure what the replacement would be, but you can try 
    SetTextureScale("_BaseColorMap")
    , or 
    SetFloat("_InvTilingScale")

    HeyjRocket,
    Code (CSharp):
    1. SetTextureScale("_BaseColorMap")
    works like a charm. Many thanks !

    This does not seem to work if you have a UV map with separate islands. As soon as you set a different scale than 1.0 in each direction, the UV map does not fit the mesh anymore. At least for me. Do you have a solution for this problem?
