Hi!
I've done a foot print system using a ray sop and some chops.
Now, I want to add a little bulge on the contour of the foot prints, like shown in the image below. I was thinking about doing it using some group selection trick…Growing the rayhit group and than substracting the rayhit group to only select the contour itself and than use a peak sop or something like that to add the bulge…

But here's a question, would it be possible to achive this effect only by using chops and to get a better control on the bulge effect using a curve to drive it?


Please, if somebodies got the answer, let me know! Scene is included below iif you guys wanna play with it.

thanks!
