Raycast problem trough the terrain

Questions & Answers
1

Well, I have searched for a solution and havent found any yet.
I’m using a raycast to check if the character gets grounded:

if(Physics.Raycast(transform.position+transform.TransformDirection(0,3,0),-transform.up,4))
     grounded=true;
else
     grounded=false;

Well, it works just fine when the character stands… When it falls it gets grounded and it wont strobe grounding and ungrounding while walking around on a terrain in different heights.

But, for some reason when I change the colliders height to half for crouching the character falls to the ground, the raycast still comes from above the terrain but it wont detect the ground anymore. ):

Crouching:

if(GetComponent<CapsuleCollider>().height!=6)
{

    GetComponent<CapsuleCollider>().height=6;
}

The standings size is 12.
Does anybody knows why it wont detect the ground? Or any other method to make the character crouch which would propably fix this issue?

Fixed it, the raycast was starting too low, it went below the terrain when the player crouched.
