A very useful workflow when using Blended Box Map involves rendering templates for further editing in a Paint program.

00:00:14 --> 00:00:22
Here's a Fire Hydrant that originated in Autodesk's 123D app and that was imported in 3ds Max as an .stl file.

00:00:23 --> 00:00:32
The geometry is fairly complex which would make it very hard to unwrap. As such, Blended Box Mapping becomes an interesting alternative.

00:00:33 --> 00:00:42
The fire hydrant is mostly red, but you may want to add scratch marks and dirt marks, or even embossed text and logos to make the model even more interesting.

00:00:43 --> 00:00:51
Press M to go to the Material Editor. There, you can see the red color material applied to the fire hydrant.

00:00:51 --> 00:00:56
Apply a single-projection Blended Box Map to its Diffuse channel.

00:00:58 --> 00:01:01
Make that color a red base color.

00:01:08 --> 00:01:15
Locate the Render Projection Templates rollout. Here you can define the resolution of images to export.

00:01:15 --> 00:01:21
The default value of 1024 pixels represents the largest dimension of the projection.

00:01:21 --> 00:01:30
In the case of a side projection of the hydrant, 1024 pixels represents the height of the image while the width is calculated automatically.

00:01:30 --> 00:01:38
The top or bottom projections would have their width set to 1024 pixels while their heights are adjusted automatically.

00:01:39 --> 00:01:41
Leave the default value unchanged for this exercise.

00:01:42 --> 00:01:47
You can also specify a name and a location for the rendered templates.

00:01:48 --> 00:01:59
Any file name you enter will be used as a prefix. 3ds Max will append the required suffixes such as _Top, _Left, _Back, etc…

00:02:01 --> 00:02:04
Once you render the templates to disk,

00:02:04 --> 00:02:09
you are ready to process them in the paint program of your choice.

00:02:14 --> 00:02:19
There, you can use various paint techniques to add dirt and scratch marks.

00:02:19 --> 00:02:25
A typical approach is to use layers set to additive or Multiply blending modes.

00:02:25 --> 00:02:33
You can then add dirt textures to create the effects that you need. Dirt textures are easy to find on the internet and many are free.

00:03:24 --> 00:03:32
Ultimately, you can also use custom brushes to create dirt and grunge effects.

00:03:56 --> 00:04:04
These edited bitmaps seen here have been provided along with the scene file. Use the link in the movie description to download the set.

00:04:04 --> 00:04:14
The beauty of this technique is that once you have edited and resaved your templates, you can then reload them in 3ds Max as part of the Blended Box Map.

00:04:15 --> 00:04:18
You could re-use the same material or create a new one.

00:04:18 --> 00:04:28
Just make sure you set the Blended Box Map to six projections, and simply use the Load Maps feature to reload the updated templates.

00:04:30 --> 00:04:35
Make sure the material is applied to the fire hydrant and render the scene.

00:04:38 --> 00:04:46
You should have by now a pretty convincing rendering without any of the hard seams that plague convention box mapping techniques.

00:04:48 --> 00:04:54
As you can see, this four-part tutorial shows how valuable and how easy it is to use the Blended Box Map.

00:04:55 --> 00:05:00
This new feature does away with the ugly seams that have traditionally plagued box mapping.

00:05:00 --> 00:05:10
The ability to render templates that you can edit in a paint program and reload into your 3D scene is extremely powerful and improves the results tenfold.

00:05:10 --> 00:05:15
It does have a few limitations, mostly with animating objects.

00:05:15 --> 00:05:23
However, given its ease of use and practicality in most situations, it is definitely a tool you should consider adopting in your future projects.
