Bump Map ,Normal Map

Hi, I tried to create a bump map for the ground texture.

I made a normal map and renamed it as it stands in the wiki, but it dont works.

WIKI:
Other texture assignments by the modeling software have no effect on the exported '_rwy.tgi' file. Instead, the shader will search for any files that have the same name but end with _bump or _specular and use them for the ground material in the rendering engine.

I did the normalmap with photoshop and compiled it with the GeoConvertHelper like in this tutorial

if I import a model, the bumpmap works, is it also possible to create a bumpmap for the Terrai texture ?
