    Help for my water

    Hi, I'm making a level in udk and I just ran in a small problem, I would like my sea material to create ripples around objects like the water in the image at the bottom of this post. I'm not even sure if this is possible with the unreal material editor but if possible in any way, i'd like to know. Thanks for any help you can give me!

    and here's my level up to now:

    Two options:

    1. Use vertex colors to manually paint water mesh in places where ripples/foam should appear

    2. If you have slopes that fall into the water you could use SceneDepth and PixelDepth nodes to determine distance of underwater geometry to the surface and use it to render shore foam/ripples.

      I had already thought of mesh painting, but What if my object is round? won't the ripples always have the same orientation? unless i could use the mesh paint to rotate my texture... I'll look into this a bit more. As for slopes, I don't have any. I just want to ripple water around big rocks that stick out of my sea, just to break the tiling a bit... I'll take a screenshot and post it up here.

        There is a third option - manually place the effects. This can be pretty easy to do and set up, but time consuming if you have a lot of edges.
