Can I also scale the zombie itself?
Yeah the scaling of the zombie remains a problem. The player capsule and camera position seem pretty objectively correct, but the problem with zombie is that the player height doesn’t match up to the mesh.
So actually the mesh is only filling about 75% of the height of the 3rd-person character. I’ve scaled everything up to about 1.2 or 1.25 bigger to account for the smaller mesh. This seems to fix it so that the character ends up being closer to 1.8 meters high - otherwise you can see that it doesn’t measure anywhere near up to 1.8 meters on the reference cubes.
