That’s right. The "Depth" parameter has nothing to with positioning the text in 3D space. You need to modify the "Z" parameter. A value of 2000 will make 36 point text very small. If you need it smaller you can use a combination of negative zoom with Z movement. You will always need to fade it at the very end to make it totally disappear.
