Bullet belt making my head spin..

Base80 did a great tutorial years ago on attaching a spline between 2 objects.

So using this and the mograph module i've made the belt feed for a gun.

But i still have a problem. As you can see the belt likes to rotate. So any ideas on how to stop it rotating?

I mike, interesting animation (ps: if you need you can attach files or movies directly to the forum, as zipped file).

I think that there is a banking problem maybe solvable with a tip goal, the continuous rotation of spline points or tangents give a strange rotation to the object...let me thinking about it

Hi,
as you have moGraph, you can try a Target effector to constraint the up vector of clones, stopping them from being tangent to the spline points, thus from rotating on every move. I think this may work

see attached files.

cheers

That looks good but i've gone in a completely new direction as i can't get both ends targeted..

After some help from elsewhere a guy called vozzz had a different idea. So here is how the cloth idea went..

The effect works, but i always feel the cloth engine seems to simulate in slow motion. What can be done about that? I am planning on using cloth quite a bit so any ideas would be great..

uhm.. personally i think spline dynamics have more natural and realistic movement for this rope-kind of things and maybe are a bit less complicated to set up.
What was the issue on constraint both ends of the spline ? You can use multiple constraint tags on different points, and have as many as you like... (just shooting in the dark, i don't know if this is the right solution for your work).
Anyway, you can adjust the stifness of the cloth to get a more flexible mesh, or raise up the gravity

hehe, wow this is old, and look its me who helped.

you guys don't get a lot of action in your english forums do you?

because the italian forum was created ten year ago, and the english forum is six months old

need to be shared over the internet

we have about 5000 english language users

but we need help for sharing c4dzone english side
