    Hey all.

    I wanna make hard height effect while using shader with map.
    Is there any sample or video or article or hint that I can follow? (even googling keyword would be okay.)
    I just assuming it gonna need vertex shader. (I'm still new to shader.)

    There's not really a good way to achieve that particular effect with shaders. Generally you'd do that with 4 cube meshes that you directly manipulate. Though you could have a grid of cube meshes that sample a texture to set position / height offsets based on a UV calculated from their world space pivot position or a unique UV baked into each cube.
