Help with Substance Painter & Unity

[levsingh]

so i recently bought substance painter for texturing my models. i designed my model in 3ds max and i exported into substance painter and applied some texture and after exporting from substance painter with unity 5 as a preset it gives me 3 png images 1. Normal Map 2. AlbedoTransparency 3. SpecularSmoothness, but when i import them in unity and apply them to the object only one texture remains eg: i drag and drop the normal map it will only show the bumpiness of the texture and them when i drag and drop another diffuse map or any other it removes the normal map and shows just the plain color. i tried searching for tutorials but i couldn't find it. HELP ME
