Hello! When I try to compile the material with PN tesselation on and with it using World Position (Excluding Material Offsets) node, it always fails displaying an error. Standard World Position and WP with excluded mat offsets when tesselation is disabled work flawlessly. Curiously, it works just fine on UE 4.25, but not on 4.26 and 4.27. Tested on both Windows and Linux.
