Hello!
I have created a crosshair that gets the same rotation as the hit point for the bullet.
It’s already working, but it look not good on the edges of objects.
Is there a way to ignore the edges or something like that?
I use this code to set the rotation for the crosshair:
// Set crosshair rotation
this.shootingRotation.copy(hit.normal).scale(-1).add(hit.point);
var vec = pc.Vec3.UP;
var dot = vec.dot(hit.normal);
if (dot > 0.999) vec = pc.Vec3.FORWARD;
this.shootingCrosshair.lookAt(this.shootingRotation, vec);

What do you mean by edges of objects?
Right there is an edge of a platform part that affected the crosshair.
That’s a tough one as all your blocks are individual entities and rigid bodies.
Don’t have a good idea at the moment tbh.
I’m still not sure what the issue is?
The raycast is somehow hitting the edge of a physics block (the floor is made up of X unit size rigidbodies) so there’s about 12 blocks in that image above.

Yes that’s right. To make easy levels I created different blocks to build the environment.
Expected result:
Actual result (on the edges):
