Importing Models into Unity

Unit set-up

Before I begin modelling anything in 3DS MAX which I intend to import into Unity I go to Customize - Unit setup, then click the System Unit Set-up tab which brings me up with this menu.

 I set my Unit Scale to 1.0 and Meters, this helps me to keep my models in scale for example height of walls and the size of rooms. This is important because when I import multiple models into unity they will piece together perfectly without having to spend time scaling them to fit together.

Here is a basic model of two planes I created which I have applied a texture and a basic bump map.

Now I open Unity and create a new project saving it to My Documents. Back in 3DX MAX I save my model to the the assets folder with in my Unity project folder. I also create a new folder with in the assets folder naming it textures and copy and paste my model texture and bump map to it.

Now when I go back to Unity my model and textures have been imported to my project tab.

Now I tick Collision Colliders and select Don't Import on the Animations Generation tab and click apply.

Now I can just drag and drop my model from the Projects tab to my scene. After that I click each plane in the Hierarchy tab. This give me the option to apply my textures to the model. I select an extra Shader option on the Shader tab and select Bumped_Diffuse. This applies another texture option below to put my bump map into. I select my textures in the 2D texture tabs and select the tiling to 3.0 on the X and Y axis of each texture, this is the result.

My model is now imported into Unity, now to add some lighting I go to GameObject - Create Other and create a Directional Light and a Point light, position them to bring out my textures and here is the final result of my 3DS MAX to Unity import test.
