See this video for example: Watch video on YouTube.

When I try to create a scene with a mesh that has no faces (removed faces from a plane so that it is a line: edges with 5 vertices). It has a cloth modifier. Below it is a plane - subdivided a few times - with a cloth collision modifier. When I run the animation playback and move the cloth object, it passes through the collision object without being affected by it.

Is there a way I can make the cloth line be affected by the collision plane?

Thanks in advance!

    $\begingroup$ Cloth (or any other simulation) calculation needs faces to be able to calculate the physics, without any faces there is no geometry to generate collisions. I am not sure, but I don't think it will work with a wire only mesh. $\endgroup$ Mar 23, 2016 at 23:37

    $\begingroup$ why are you trying to use a mesh without faces? Maybe there is an alternative solution to what you want, that's why I'm asking $\endgroup$

While you can't do collisions with edge only mesh objects, to get around this I just add "tags" to my vertices. They are small triangular faces that allow for the collisions to be calculated.

Then I either enable collisions on my base mesh or add dummy faces with collisions parented to the base mesh.

Yes.Cloth simulations need faces to work due to the Spring and Stiffness algorithms that it needs to work out between verts in opposing corners of faces.
