applying textures to meshes from blender?

I’m fairly new to unity and everything but for the most part I know how it works. One problem I’m having though is applying my textures to it and making it look great. I figured out how to do some of it by making a material and applying a bumped diffuse shader to it. But when I do this all it lets me do is use my color and normal map textures. What kind of shader would I use for my displacement, specularity, and occlusion? My object looks really ugly when I just use the bumped specular shader and doesn’t look anything how my finished result looked in blender.


Depending on the shader, you have to put some of your maps (specular for example) into the Alpha channel of RGB
