Scaling modes
When editing textures in the Object Inspector, you have a choice of two modes for the
Scaling Type—Pixel mode and Tile mode.
In Pixel mode, the physical size of an image is determined by the number of pixels—the
more pixels, the bigger the image. In the Objects Inspector, the Scale values are the size of
a single pixel, expressed in length units. The Offset values are specified in numbers of
pixels.
In Tile mode, the physical size is independent of the number of pixels in the image. In the
Objects Inspector, the Scale values are the size of the image, in length units. The Offset
values are also measured in length units.
If you find that you're using different variations of a texture, you can add multiple
versions of the texture to the Variable Tools palette, and then adjust the settings for each
texture.
Scaling textures
A texture's scale is an important factor in creating realistic objects. For example, if you
apply a brick texture to a wall, the size of the bricks should be proportional to the size of
the wall. Or if you use a forest texture to create a natural environment, the trees should be
proportional to the other objects in the world.
To specify texture scale in the Variable Tools palette:
Select Browser view.
1
Select the texture you want to scale in the Variable Tools palette.
2
In the Object Inspector palette, make sure the Scaling Type is set to the mode you wish
3
to edit in. See "Scaling modes" on page 47.
4 Specify your scaling options by selecting:
• Scale with Object to have the texture scale proportionately when an object is scaled.
• Constrain Proportions to uniformly scale the U (horizontal) and V (vertical) texture
coordinates together.
