Hello everyone

I am trying to animate some A4 sheets of paper flying like the image attached.
The whole scene is built with c4d 12 and the problem I have is that the sheets of paper do not collide with each other.
Could you tell me what is wrong with it?

Thanks

Here is the file I am building

I think to be having colissions you need to be using dynamics tags.

[Horganovski]

For cloth to cloth collisions to work all of the meshes need to be Connected into one mesh. You can do this using the Connect and Delete command after selecting them all. Then make sure to enable self collision in the expert tab of the cloth tag. You'll need a pretty powerful computer to be able to handle this kind of thing though if you want a look like your image with a so many pages.

Edit- here's an example.

Hi Brian,

Your 'Connect' method works well.

Edit: This is interesting as although the planes are connected as one they are still independent as far as the forces acting upon them. Perhaps I am not understanding what 'Connect' actually does, can you explain please?

I tried putting Cloth Collider tags on each plane and that doesn't work at all for some reason.

It's usually best to use Cloth NURBS rather than HyperNURBS or a combination of the two and Cloth tag > Expert > Increasing 'Sub Sampling' can sometimes help reduce mesh penetrations if they are occuring.

Cheers,
