    [UE4.22] Bug? Landscape Grass Type not rendered

    Hello,
    I'm not sure if it is a bug or a feature xD, but when dithered lod transition is activated on the material of a Landscape Grass Type the meshes wont be rendered in UE4.22.

    How to reproduce it:
    1: create landscape
    2: create a material for the grass and activate dithered lod transition
    3: assign that material to the grass mesh
    4: create a Landscape Grass Type
    5: assign the grass mesh to the Landscape Grass Type
    6: create a landscape material and add a grass output
    7: assign the LAndscape Grass Type to the grass output

    activate and deactivate the dithered lod transition in the material of the grass, you will see, the grass is not rendered when it is activated.

    I made small example project: try it there

    Edit:
    Is there something I have not seen it in the documentation? Is it wrong to use dithered lod transation for grass?
    This problem is just in UE4.22.
    Please help me ;-)

      Got a mail from Epic. It seems to be a bug in 4.22. Should be fixed with the next release.

        I thought "the next release" would be 4.22.1 but it's still bugged
        now it's not completely invisible but partially
