Hi,

Can anyone explain how to use intersect from Terrain Tools to get ripples to form around an object as in the example image on DCG's website (http://www.digitalcarversguild.com/gallery/ttripples.jpg).

I just can't seem to get it to work. I'm not 100% sure where to add the intersect.

Thanks.

Mark

In the bump channel of the water plane, tell it to intersect with the sphere.

Thanks Patrick.

I've added intersect to the bump channel but nothing seems to happen. I've posted my shader in case I've set it up wrongly.

The secret is in the Falloff... edit it to a sine wave form and do a render.

Thanks, I'll give that a try tonight.
