Hi again, and thx for helping again !
sadly, use static lighting is checked true.
but to my suprise, if i add a ue4 sphere object to the scene and apply the tesselated material to it, it works !
so there seems to be a problem the material is applied to the mesh, because in ue4.7 everything worked without any flaw.
the bridge is part of a static mesh, i exported from 3dsmax via fbx.
here is the file, if that helps …

i had scaling wrong in 3dsmax, so i had to use a scale-factor of 0,01 in ue4.
but this couldnt be the problem, because in other scenes i had scaling right and the material doesnt work there ,too …
hope you can make something out of this
kind regards stucki
