Making a Shaped Water Ripple in ZBrush and Photoshop

So I’m working on this piece with a guy floating in the water and thought I’d share the workflow I used to make the simple water ripple around his body. Within ZBrush, have your water plane and object meeting and then take a screenshot from above with perspective off. Open the screenshot in Photoshop, crop it to square – since you’ll be making an alpha map for your brush – and then use outline as a selection. Offset the selection, stroke it and blur, and you now have an alpha map for ZBrush:

My water cube is too small but it’s just for a still, so I can clone out that wonky bit at the top. Also, water has an index of refraction of 1.333 but I used 1.6 to increase the refractive effect since I’m not going for realism. As you can see in the video, I like to use Smart Objects for my Photoshop layers since the blur filter can always be changed later if I want less or more of the filter and I can scale the stroked layers non-destructively.
