Unexpected behaviour of RayIntersectsSphere

[chk]

Actually not really sure if I am getting something wrong, but I expected the Vector3 of the RayIntersectsSphere to be where ray and sphere meet, is this a bug?

Thanks! :) And why?

[Hadasi]

When working with calculations involving rays the magnitude (length) of the Ray is calculated should be 1. I dunno, maths innit!

Maybe this helpful to somebody in the future.

Sorry I have to come back to this… this time I use a normalized vector, but with a direction which is clearly shooting past the sphere. Am I still missing something here?

in the patch you attached, the Normalize node is missing. if you add it, it works as expected.
