  • Resolve Water Pushing Through Lily Pad While Rippling

    Posted by Jay Ingles on February 26, 2012 at 6:39 pm

    Hi,

    I’ve built a simple lily pad with a water ripple in a white, reflective environment but can’t figure out how to get the water to not push through the lilypad object.

    I’ve tried merging the objects, separating them slightly, and considered boolean but don’t feel that is the right approach as i suspect it’ll cause shadows/AO issues.

    Any suggestions are appreciated!
    thanks.

    Hmm, the link got abbreviated somehow.

    Seems like a good application for dynamics or cloth. You could put a cloth tag on the lily pad and a cloth collider on the water. Or if you want it to be more rigid you could use soft-body dynamics.

    Thanks. Would you build it the way i did with a circular pad and square “active ripple area” to be affected?

    My thoughts were that i can then drop it wherever in the scene. Also that it might lower render times since ripples were only affecting one controlled higher poly area.

    To elaborate on the cloth idea, keep the floor as is and using the cloth tag drop the lily pad on top of the floor. Then when the forumula moves it shouldn’t protrude through the cloth. Correct?

    Great idea. thanks

    the quick and dirty way is to control the center of your vertex map so instead of just making the ripples falloff with distance you kill the ripples under the lily pad

    Interesting, i hadn’t realized the potential of pulling the vertex weight to 0%.

    I’m noticing now that the behaviour is rather unrealistic. the ripple fades up at full ripple instead of being triggered by a drop and have 1 series of rings expanding.

    Is there a solution for this using the formula approach? Or is the alternative a soft body map with an elastic material being hit but an object?

    Thanks.
