Solution: Although the Compact Material Editor can only display a maximum of 24 unique materials at once, you can create new, 'empty' material slots by resetting some or all of your current displayed materials. (The Slate Material Editor can display an unlimited number of materials created in the workspace.) Note: resetting the Compact Material Editor sample slots does not remove the materials. Material Map Slots Explanation. When creating materials, all texture files loaded need to be in.dds format. To open the Material browser, press “M” on your keyboard within 3ds Max. Change “Blinn” to “Phong” under Shader Basic Parameters (See Fig 3). Name this ´myWallMtl´. (Note: to easily export from 3ds Max to your game engine you might want to use a 3ds Max standard material instead. Many exporters have better support for the standard material). Open ´myMultiSub´ material again. Add ´myWallMtl´ to slots 2,3,4,5 of myMultiSub. As for the upgrade, if you go into the base menu and click on the square with your beds, there should be a square with an arrow pointing up. If you click it, it will tell you you can add one bed.

Natural Variations

Why 2 tutorials for natural variations ? One for game artists - another one for architects ? Because game artists need a much more weathered look. Why are large scale variations so important for better renderings? Without variations buildings look monotonous, less realistic. Even adding tons of texture does not solve this. In any case also have a look at the RTT tutorial, which shows how to bake RichDirt results to a texture.
What causes large scale variations in the real world? Buildings get a ´tint´ from weathering via wind. Wind is stronger at the edges of a building and at the top, with strong impact on dust, dirt, rain. This tutorial shows how to easily add this effect with RichDirt. Break da bank free slots.

More Advantages of the approach described here are:

no manual painting required (save time)
no memory for huge textures required
fast rendering
single setup for many different materials
no precise uv mapping required

1. Load the tutorial scene

For V-Ray click here. For mental ray here. For 2016,15,14,13,12,11 and V-Ray click here for mr click here Old versions show warnings , ignore these please. Make sure you have gamma and LUT correction enabled for 3ds Max. Select Camera001. Render the scene:

Expert users can skip items 2 to 6.

2. Open the Compact Material Editor.

Create a new Multi/Sub Object material. Name this ´myMultiSub´.

3. Create a new V-Ray material or mental ray Arch and Design material.

Name this ´myWallMtl´. (Note: to easily export from 3ds Max to your game engine you might want to use a 3ds Max standard material instead. Many exporters have better support for the standard material).

4. Open ´myMultiSub´ material again.

Add ´myWallMtl´ to slots 2,3,4,5 of myMultiSub. Make sure to use -instances- (not copy, we want the same wall material used 4 times). Note: add can be done via drag and drop in 3ds Max. Your ´myMultiSub´ should now look like:

4b. Assign myMultiSub to the building

Select the 2 walls in the viewport. In the material editor press the ´Assign Material to Selection´ button.

5. Now go back to ´myWallMtl´.

Click the diffuse color map button, to add a RichDirt texture. Name the new texture ´WallDirt´.

6. Make the Dirt color -green-

Green is used here so it is easier to see the effect. Also change the ´Clean´ color to rgb 0.973, 0.851, 0.612. Select the ´Rich Building´ preset.

If everything worked fine the image should look like below. Note that V-Ray might add global illumination, then the image can even look better.

7. This image looks good ..

(except for the windows) but we still don´t have a ´large scale variation´ - the structures around the windows are identical all over the facade. The building edges have also the same intensity top+bottom, left+right.
How to add the large scale variations ? The following part of the tutorial dives deeper into realistic weathering. Step by step. Game Artists tune a city with all its buildings - use RichDirt with the steps below to get as much extra effects as possible, for free when doing texture baking.

8. Adding a large scale variation.

Our goal is to make it realistic, and we know that wind + rain + dust are the real forces for these variations. Click the RichDirt Radius map button - to add a Bitmap. You find the Radius map in the main rollup. To download the wind.jpg from this website select it and right-mouse + save. This works in most browsers.

Wind.jpg needs must be maped to the full facade. Create the bitmap for the ´radius´ multiplier (RichDirt main rollup). Select the main geometry, add a UV map modifier. Use box mapping, make the box match with the building, especially the upper edge should match. In the bitmap texture make sure ´Mapping´ is set to ´Explicit Map Channel´ and ´Map Channel´ is 1. The uv modifiers values are used by the bitmap that way. Render to get the following image:

9. Does the image above look real ? No ! Why ?

On real buildings more dirt is found in the lower part, as wind is slower and less rain washes less dirt away. How do we get this effect ? It is easy in 3ds Max. Make a copy of the wind bitmap. Invert the bitmap, but do -not- use the ´invert´ button - switch on ´Color map´ instead, and invert the function below by dragging left control point to 1.0, and the right control point to 0.0: How to get more material slots in 3ds max 4

10. Also adjust the output ´RGB Offset´ to 0.5.

What for ? The offset is to make sure the upper part of the texture isn´t completly black. Black would cause a radius of 0 cm (0 * 50 cm) , so inner occlusion wouldn´t find obstacles. Easy: Playing with amount and offset you can control how dirt is distributed over the building. If you weather several buildings of a city simply modify the rgb offset and you have a nice variation.

10.b Add the mirror material for the windows.

The tutorial uses a multi-sub material. The scene uses a single mesh, to assign a glass material assign it to id 6 of the multi-sub material. By chance the windows have id 6. VRayMtl: Diffuse black, Reflect white. Ior 2.0. Or use an arch + design material: Diffuse 0.0, Reflectivity 1.0. Ior 2.0, Brdf by ior.

11. Now add streaks.

How To Get More Material Slots In 3ds Max Walkthrough

Go back to the myWallMtl. We need a composite map with 2 dirts in it. Single steps: In the diffuse slot create a 3ds Max composite map. This isnt directly possible in the compact material editor. Right-mouse on the map button. First say ´copy´ for the existing richdirt map in the slot. Then say ´clear´. Then left-mouse the map button. Choose the composite map. Once inside the composite map right-mouse the big area on the left side, and select ´Paste Instance´. This uses the copied green dirt from above. Add a second layer for streaks (there is a little + sign in the upper right corner). Create a new RichDirt, select Preset ´Below Bench (strong)´. Use red as its dirt color. Switch on io in the main rollup (some of the benches are small so they are only found by io rays). Make sure the composite mode for the new layer is ´darken´. Render:

Hm, no streaks visible - what happened ? IO dirt covers AO streaks - We forgot to enable streaks ´For IO´ in the streaks rollup. Do that now. Render:

12. The next step is for dirt aficionados.

It shows how to add even more realism. Background - the streaks we have so far run down from the benches in a very even way. Real world benches have an area
