Setup Blueprints in 3DS MAX

Going to 3ds Max

Open 3ds max and go into the material editor click the first material.
Tip: Material editor can be accessed using the M key on your keyboard.

Then the select the box that says "Standard" when this is clicked it reveals the Material/map browser from there select "Multi/Sub object" and Discard the old material and click ok.

Moving on we want to change the amount of materials we have in this section these will be our images so go ahead and change the value under the "Set Number" button. For this example i am selecting four yours may differ depending how many views you had on your original blueprint.

Column "Name" and row "1" = Top
Column "Name" and row "2" = Back
Column "Name" and row "3" = Side
Column "Name" and row "4" = Front

Now that’s done we can start editing the materials for the sub objects. Select the Material next to your material named top.

We now notice that it has changed to a Standard material at the moment your material looks like this

+Main material--
-----Sub-Material ---Top <== This is where you are at the moment
-----Sub-Material ---Back
-----Sub-Material ---Side
-----Sub-Material ---Front

Click on the little box next to the diffuse colour and select Bitmap from the Material/map browser

You want to now select the Image we saved earlier we are in the top material so it makes sense to select
the top view of the four images

Now click the chequered box this will enable the bitmap to be visible in the viewport

Next, back to the Main material by clicking Go to Parent which is this button here

Now repeat the steps for Back, Side and Front and changing the Bitmap for each materials.
