Shadow line problem a spotlight makes - how can I soften this?

[hoptimist13]

Hi, I'm using a spotlight for the main light,
But I see this distinct shadow separation line whenever spot a cylinder.
I gave falloff to the spotlight but failed to soften this line.

Anyone can give me some wisdom for this?

What's your light radius on that spotlight?
Have you ever seen a soft shadow from a really bright LED coming from a single point?

Your light source needs to be larger and/or further away.
