Ok i have a model that is exported as .fbx from max, and its backwards in my game.
when i use code to reverse the LookAt the model moves backwards with a Vector3.Forward. if i use Vector3(0,0,-1) it moves sideways :shock:
if Vector3.Forward is moving the object away from the look at i hacked up to change the npcs rotation, how could i get it to move backwards 
im really stumped on this, could anyone lend a hand?
Couldnât you just rotate your model 180 degrees from within your 3d modelling program and re-export the fbx? Seems like that would be the easier thing to do. Otherwise if âVector3.forwardâ moves the object backward⌠â-Vector3.forwardâ should move it backward?
Then again, your coding could get confusing since your translations would be backwards.
yeah i tried to to that to move it backwards but then he moves sideways? but when i just do it normally its as if hes running away cause he moved right back, which made no sense to me. it was like , working more right when he was moving the opposite direction
and for the life of me i cannot figure out how to rotate the model in max 9. i have to rotate every frame, when i rotate it and change to the next frame, the first one i rotated has reverted.
also if i go to mirror XY then it rotates the frame around, but the same issue i cannot get all the frames rotated and exported.
Also, you can try rotating the object 180 degrees using eulerAngles after you do the LookAt.
Like so,
transform.LookAt(target);
// Force the object to rotate 180 about the Y-axis
transform.eulerAngles = new Vector3(transform.eulerAngles.x, 180, transform.eulerAngles.z);
hmm
i tried to rotate the whole object doing that
follower.eulerAngles = new Vector3(follower.eulerAngles.x, 180, follower.eulerAngles.z );
and just the mesh attached to the object,
GameObject.Find(âSLUGâ).transform.eulerAngles = new Vector3(GameObject.Find(âSLUGâ).transform.eulerAngles.x, 180, GameObject.Find(âSLUGâ).transform.eulerAngles.z);
but neither really worked
Can you post the whole script?

i try two different methods, one in chase and on in walking. neither work.
follower is the transform of the slug monster, but SLUG (when i do gameobject.find) is just the mesh, or atleast when i rotate that in the ide it rotates the mesh.
and if i rotate it in the ide then it doesnt help at all, ive tried it.
Sadly, i have similiar issues. I end up parenting anything i export out of lightwave to a null object.
When itâs in unity, i can simply rotate the main object to 0,0,0 then adjust the rotation of the null object to whatever will make the object âcorrectâ in unity. Not a perm fix, but might get you by.
i figured it out with this expression
apoint = leader.position;
apoint = 2.0 * follower.position - apoint;
follower.LookAt(apoint);
to look in the opposite direction
and i did a -Vector3.forward to move backwards, but in effect, moving my model towards the camera, facing the camera.
yay!
Just change the speed variable to a negative.
did that already its working now tho, thanks guys.
