8. Assign a Combustion map to the Diffuse
component of the sub-material applied to the
selected faces.
9. Click Edit to launch Combustion.

To modify a Combustion map:
1.
In the Material Editor, select the m aterial you
want to modify.
Material maps created in Combustion are
vector-based and fully modifiable.
2. In the Combustion Parameters rollout, click the
Edit button.
The workspace corresponding to the
Combustion m ap opens in Combustion. As
you modify the workspace in Combustion t he
map is updated in 3ds Max.
3. In Combustion, save the workspace before you
disable the Edit button in 3ds Max.
To create a dis pla cement map:
In 3ds Max, the Displace modifier (page 1–608)
acts as a force field to push and reshape an object’s
geometry. You can apply its variable force directly
from the modifier gizmo, from a bitmap image, or
from a Combustion workspace.
The grayscale component of the image is used to
generate the displacement. Lighter colors in the
image push outward more strongly than darker
colors, resulting in a 3D displacement of the
geometry.
1. In 3ds Max, select the object to which you want
to apply the displacement map.
In this example, the displacement is applied to
a box primitive.
In the object’s Parameters rollout, i ncrease the
number of Length and Width Segments. The
closer the number of segments approaches the
resolution of the displacement map, the more
accurate is the result.
In the example, 150 by 150 gives good results.
2. Apply a Displace modifier: in the Modify panel,
choose Displace f rom the Modifier drop-down
list.
3. In the Parameters rollout, Image group, click
the Map button.
