I am trying to make an animation using soft bodies, but the problem is that they are passing through each other. I have turned on Collision in the physics panel. Thanks. Blend File
You also need to enable "Rigid body" for each of the objects
Select your object, go in Edit mode, select all and press W > Subdivide, same for the other one, it works, I guess the objects need to be a bit subdivided to interact properly with each others.
Solved. I just needed to check 'Faces' option in 'Soft Body Edges' settings.
