How to create a spherical lithophane I'm trying to create a spherical lithophane in Blender 2.80 for 3d printing. I can create a sphere and hollow it out, but the inside of the sphere has the same texture as the outside (For a lithophane one side of the surface has to be smooth). I have created the sphere used displacement to create the surface texture, and then subtracted a smaller sphere from it to hollow it out. Trouble is the hollowed sphere then has the same texture as the outside. I hope this makes sense to somebody and you can let me know where I am going wrong.
Cheers

Create vertex groups - go into the weight editing mode, select the outer part L and assign a weight to it shiftK (when vertices are selected).
And select this group in displacement modifier
