Unity SphereCast - Getting the center of the last sphere before the hit

Question

Hello, I'm new to Unity.

I'm working on a game that looks like bowling. My problem is about the Raycast. I'm trying to make a line for the ball to show it's path before the ball is thrown. Physics.Raycast won't give me accurate results because my ball has radius and Raycast doesn't. So I'm using SphereCast. The problem is I can't get the center of the latest Sphere before hitting a collider. With that center I can draw a line from my ball and this center.

I'm searching for this for a long time but couldn't find any answers.!

I put a photo to show the problem as I can. When I write hit.point, unity is giving me yellow position as it should but I want red position. alt text

A RaycastHit has the field "point" and "normal".

 RaycastHit hit;
 
 //do your Spherecast...
 
 Vector3 center = hit.point + radius * hit.normal

Care: not tested ;) But this should work :)

hit.normal is the normal of the surface, not the direction to the sphere that collided. In this example it works, but in any other the results are not what's expected.
