Using bump maps
Bump map is a term describing an image file that, when applied to a text or path
object, creates the appearance of 3D grooves and extrusions on the surface. The
darker a particular region is, the deeper the groove, while the lighter a region is,
the higher the extrusion appears.
To add a bump map texture to an object:
1. Create a 3D path object or 3D text.
2. Click Material and select Bump.
3. Click Bump map, then locate the file you want to use as a bump map and click
Open.
4. Enter the Density of the bump, where 100% is the maximum and 0% is the
minimum.
5. If the 3D path object has texture,
select Displacement mapping to
give the object a more realistic
appearance. Change the X and Y
values to adjust the texture's
displacement over the bump map.
6. Clear the Use bump as reflection
option if the object has a flat surface.
However, if your object has a round
or curved surface, select this option
to map the image across the entire
surface.
7. Select Invert bump map to make the image appear raised instead of carved
out of the surface of the object.
8. Click OK.
Saving material properties to the EasyPalette
After enhancing text and path objects using the Material dialog box, you can save
custom attributes and 3D properties in the EasyPalette for future use. If you find
that you use a particular look or effect frequently for text or path objects, this will
help you save time by providing you with that effect ready to be used, instead of
having to recreate the effect each time from scratch.
