so you want this vector to be relative to the camera rotation?

[icy mango]

Yes

[stable copper]

making the Y value rotation.y doesnt really help you

[icy mango]

that's just debug

[stable copper]

you can multiply a quaternion by a vector to rotate it

So I should multiply camera with The converted grid? or other way around?

[stable copper]

im still kinda confused as to what this is supposed to be doing

[icy mango]

Basicially shoot a grid of rays relative to the camera

[stable copper]

multiply your new Vector3 by the camera transform.rotation

that might do it
