I've read/heard elsewhere that the Subsurface Scattering in the Principled BSDF Shader only works if a Solidify Modifier is present. Is this correct?
If I create a flat Mesh Plane e.g. it would make sense that I need to apply a Solidify Modifier for Subsurface Scattering via the Principled BSDF to have an effect.
However, If I created a Mesh Sphere -- or Cube or any non 2D or non-flat object -- do I also need to add the Solidify Modifier for the Subsurface Scattering via the Principled Shader to have any effect?
