Activity Forums Maxon Cinema 4D Metaball issue

  • Metaball issue

    Posted by Scott Gaskin on May 6, 2017 at 8:16 pm

    Hi guys

    I’m having an issue with C4D whereby I’m using metaballs to create a drip down the surface of my object. I firstly created 2 spheres and used a constraint tag so the spheres would follow the curvature of my object. This worked fine until I added the metaball and the spheres now disappear into the middle of my object before appearing again at the bottom rather than being constrained to the surface. Any ideas what Im doing wrong?
    Thanks Scott

    change the Priority of the Constraint tags on the spheres to Generators -499 so the clamp happens before the Metaball gets to run

    Thanks so much for this Brian that has fixed it. Is there any guidance info that you can point me to that explains this in more detail? The information has gone right over my head and could do with trying to understand this more for future projects.

    I originally followed the below tutorial to understand how to constrain objects to follow the surface of another object and it suggested to change the priority to around 150 as the object could randomly move or get knocked out of place.

    Really appreciate your help with this

    Go to the Constraint tag’s basic tab and right-click on the word “priority”, and then click on “show help” in the pop up menu. You’ll get a basic explanation of priorities in Cinema.
