    "Sample Texture2D" + "Set Position" dose not work like "Set Position from Map".
    I need to use former, but it was not work as expected.
    "Set Position from Map" was as expected.

    Please tell me the difference.

    It was solved. The cause is Texture Filter Mode.

    hi, s-makino.
    I do some work with "position map", and i wonder how you create your position texture? can you control the position of every particle, or just make a random texture like Perlin-noise?


    and by the way, are you japanese?
