nice work!!!!
i tried it in my own project, but i couldn’t get it to work properly…but this is my fault, not yours.
your example works really well.
I see! In Construct, layers trump Z-elevation, which can break the perspective. In order for Z-elevation to work with perspective the objects whose Z-elevation you want to manipulate (with my addon or manually or in another way) have to belong to the same layer.
This gave me headaches so many times…!
