Raycast not working on certain sides of parts

[TGVBHJJ]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   code no work

2. What is the issue? Include screenshots / videos if possible!
   
   I’m using raycasting to detect when a wall is infront of my rig, but the raycast only detects the wall on certain sides. (The green rods are where the rig detected a wall)

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I’ve tried moving the start of the raycast to slightly behind the rig and changing the rotation and position of the parts.

Once again, someone still misunderstands what RayDirection parameter does. It’s supposed to be one unit of a direction multiplied by length or distance.

You need to convert pos to a singular unit using Vector3.Unit and then multiply it with a number of choice for how far in front of you.
