I don’t know where the problem lies. Is it a camera issue, an animation issue, or a meta/humanoid component issue?
In version 5.4 of the engine, when I change the Ortho Width of a component attached to the camera to create a pixilation effect and raise the result above 2000, all metahumans components become distorted.
