Problem

How can I adjust a material pattern map to have the correct scale

For Example: Brick materials are not the correct size.

Solution

Change the material Units to "Master" and change the size the texture map so that a single iteration of the material measure correctly in master units.

How to change the size of a texture map:
1. From Menu bar, go to Settings > Rendering > Materials [ Material Editor opens]
2. Click the Pattern settings button (located to the right of the "Color" slider) [Pattern dialog opens] .
3. In Mapping Section, change Units to "Master".
4. Change values in X and Y size to get correct size for image.

Example of getting desired size for materials:
Using a brick type image, the desired size of a single brick is 16 inches long and 8 inches tall.

1. View a single iteration of the image (MicroStation Image viewer - From menu bar, go to Utilities > Image > Display).
2. Count the amount of bricks that appear across width and height of image including partial bricks (for example 6 for Y and 3 for Y).

The desired length and height of 1 brick is 16 inches long x 8 inches high. There is 6 total bricks in the length of the image and 3 in the height. If this image is measured in real size, given what is known about the bricks, it should measure 96 X 24 inches.
Note: Mortor thickness is ignored in this example.

3. 6 X 16 = 96 inches (or 8 feet)
4. 3 X 8 = 24 inches (or 2 Feet)
5. In Pattern Settings, enter 96.0 (or 8.0) for X and 24.0 (or 2.0) for Y.
6. Close Pattern settings dialog
7. Save Palette (.PAL) file.

Note:
The Master Unit value in the file is what the material system uses when set to "Master". For example, if the desired measurements for the brick are in inches, but the master unit is feet, will need to divide the desired image size by 12 to be correct.
