@Ellement,
as shando mentioned, you need to be using an advanced material in order to use normals and specular.
but if that doesn't work and normals still dont show, then it is most likely tangents for each set of vertices.
This is required for normal and displacement mapping.
If you cant generate tangents on your mesh inside the modelling application, then you could use Skyline's tangent generating tool.
To use this:
> Go to and click on "main menu -> Tools -> Mesh -> Generate tangents on selected Entity".
> Reload the scene entity using the icon on the toolbar. (E with a refresh icon on it).
As for displacement mapping, this is currently in development and not usable by yourself atm unless you write your own base material. But we will be introducing it soon as we have a lot of shader work to do
Hope this helps
