Clone a cylinder to each poly?

Recommended Posts

I meant to ask this last night. I'm away from my computer at the moment, but I got stumped last night trying to figure out how to clone one of these cylinders into the middle of each polygon on the surface. I think the reason I'm having extra trouble is because I don't want them right on the surface, but instead sticking through into the octahedron shape a short ways because I want to boole a bunch of divots out of it. I'm sure someone knows how to achieve this with very little headache.

Create a cloner and simply clone onto the spheres polygon centers. Then you can convert the cloner and connect all the cylinders into single object and boole the sphere

  • But here's the problem. How do I get them facing out, so they'll make nice neat holes in each polygon? I tried adjust [up vector] and it just gives them other alignments that aren't helpful either.

    "Align Clone" checked, "Up Vector" None, "Distribution" Polygon Center - this will use the poly's surface normal to make the clone's z axis point outward. The cylinders need to be oriented in the z axis, naturally.

  • That's what was wrong. My cylinders were oriented in the default Y+ axis. I wonder why they don't give you the option to check which orientation you'd like to use. Such a simple problem, but if you don't think of it because that's just how c4d defaults to making cylinders you'd never know.

    They do. See object attributes of the cylinder.

  • well yeah, but I mean in the cloner HAHA. It just didn't dawn on me that you'd have to use the cylinder's orientation to direct how the clones went. now that I see it it's obvious, but I kept looking in the cloner settings for it. thanks for the help guys.

    Yep, you can do it in the cloner as well ! (Transform tab).
