How do I mirror a sprite and make it mirror in the 3d object too?

x > playercollision.x - bosscollision dont mirror sprite

x < playercollision.x bosscolision.x mirror sprite

but this dont work (nothing happens in the 3d object). can somebodu help me please

Set the face object to a sprite. Make that sprite have 2 frames (not mirrored, and mirrored). Set the animation speed to 0. Then all you have to do is whenever you want to mirror the 3d face, just switch the sprite to the second frame. :)
