Soft Body Physics - Ball is not falling instead just doing harmonic motion

I made this rigid body static plane

And then a soft body ball. Got the vertex group thing also done

But when I animate, it just does harmonic motion and doesn’t fall. Why?

I used wind force via Empty, even then it is come down little bit and then again harmonic motion

Most likely you enabled “soft body goal”. If you have goal enabled, the softbody will try to conform to that goal.

Thanks Lommbard, you were right. I unchecked Soft Goal and it worked.

But now the new problem is that the ball went through the plane without colliding with it. The plane was a rigid-passive body

For a softbody to collide with another object, you have to make it a collision object in the physics tab.

The documentation is pretty good on this:
