Mac OSX 10.13. Error occurs in Corona B1 and latest B2.
I'm trying to make a stacked material. The 'bottom' material has displacement and the 'top' had the main material.
If the displaced material is on top, it is mapped correctly (using flat projection, no tiling, front only). As soon as you move it to the bottom (which is necessary for the displacement to work in the hierarchy), the mapping jumps to a totally different place.
Hopefully the screengrab illustrates this better than my wording!
