Terrain bumped specular material not working


i want to apply normal maps to my textures on the terrain. i created a Nature/Terrain/Bumped Specular material and applied it to Terrain Settings> Material slot but i don’t see any change in the terrain. all the textures i added to the terrain have normal maps (created /w CrazyBump).

i’ve checked everywhere but no one else seems to be having this problem

thanks in advance

weird! it worked in a new project with a new scene… really have no idea why but this might save someone from wasting their time trying to figure it out
