Change to how the X value for the camera position is handled in the template strings. BabylonJS and ThreeJS use different coordinate systems, so inverting the X value is needed for one of them.
Because the screenshot generator uses BabylonJS but was not inverting the X position of the camera, the sample images didn't match the viewer versions of the same models. This corrects that discrepancy.
