How to create a round path in 3D?

Unity Engine
1

I’m making my path for a game with Cinema 4D and I do not know how to make a round path because the segments are “square”.

Any ideas?

Thanks!

Do you mean you want to plot a smooth curve through or between a set of points (rather than a zigzag “polyline”)? There is a script in this thread that implements Bezier curves and Catmull-Rom splines, either of which might be useful depending on what you need to do.

Yeah, the first one option (a smooth curve). You can see the edited screenshot. As I said I would like to creat a smooth curve in Cinema 4D. Do you know the solution?

Thanks for help and patience!

Just yesterday I was trying to accomplish the same thing in 3ds Max. What I cam up with was a line, which I exported and brought into Unity. I then used

var vertices = transform.gameObject.GetComponent(MeshFilter).mesh.vertices;

to get the vertices of the mesh. max exported it as points rather then curves, so I wound up with 60 or so verts listed in order around my curves.

I assume that is what Andeeee is refering to. You can simply make a curve in Cinema4d and export it as a mesh. If you cannot do that with it, then create a mesh. assign it verts in order and let Andeeee’s script parse the curves for you. The key would be to have the verts in order.

Hope that helps

Buff, it’s too much for me. I’m just new (better known as n00b). There must be a simpler way to do it in Cinema 4D.

Thanks anyway.

you should ask this in a Cineman 4D forum.

There’s a plugin for unity to create roads, if this is what you are trying to do.

There’s no official Cinema 4D forum :frowning:

You can ask on C4DCafe. Although it’s not an official forum, it’s the best one out there. Folks there are very friendly and will help you out.
