I am using layers that change or increase value Z.
aside from the HUD layer, all the others have parallax 0.0.
In addition to the layers that change the Zelevation order , there are other layers behind that do not change their values in the Zelevation.
initially the layers have Zelevation in the values:
upper layer value: 0
intermediate layer value -48
bottom layer value -96
When you press a button, the layers gradually change to the values:
upper layer value: 96
intermediate layer value 48
bottom layer value 0
Whenever layers have a negative value at Zelevation, the other deeper layers get parallax that cannot be controlled.
at 0:30 seconds of video i show that layer over 0 has no parallax effect
