Placing Animated SimObjects With World Script Above Ground Level

Hi! Does anybody know how I can place a world script object above ground
level? This is a 3D Human and need it to be over the ground to match the
Terminal floor, I’ve set the height in the Z parameter in the .xml file, but
it always shows up on ground level. Any help? Thanks.

Same if I try to move above the ground my SimObjects, they are stuck into the
ground even if I set an offset, any idea why? Thanks!
