Autodesk Bitmap for Autodesk Materials

A bitmap provided as a map for many Autodesk Materials.

• Material Editor > Material/Map Browser > Materials > Autodesk > Choose an Autodesk Material that uses maps.

The Autodesk Bitmap always uses real-world mapping coordinates. If you apply it to an object that has a UVW Map modifier applied to it, be sure to turn on Real-World Map Size.

Attention: When an Autodesk Material has “built-in” Autodesk Bitmaps, you can disconnect these or replace them with other 3ds Max map types, but be aware that when you do so, the resulting material will not be compatible with other Autodesk applications. To maintain compatibility across products, leave the Autodesk Bitmaps connected to the Autodesk Material.

Interface

Parameters rollout

Source

Opens a Select Bitmap Image File dialog so you can choose an image file to use for the map. You can choose any file type that 3ds Max supports.

Note: For Autodesk Bitmap images, 3ds Max disregards the gamma setting.

Brightness

You can use the brightness slider or numeric field to decrease the brightness of the image. At the default of 100 percent, the map has its original tones. Default=100.0 percent.

Invert Image

Inverts the colors of the image.

Position rollout

X, Y

Offset the image along the local XY axes in 3ds Max units.

Rotate

Rotates the image around the local Z axis. Default=0.0.

Scale rollout

Width, Height

Specify a width and height for the image in 3ds Max units.

Repeat rollout

Horizontal

When on, tiles the image horizontally. Default=on.

Vertical

When on, tiles the image vertically. Default=on.

Advanced Parameters rollout

Blur

Affects the sharpness or blurriness of the map based on its distance from the view. The farther away the map is, the greater the blurring. The Blur value blurs maps in world space. Blur is primarily used to avoid aliasing. Range: 0.01 to 100. Default=0.1.

Blur Offset

Affects the sharpness or blurriness of the map without regard to its distance from the view. Blur Offset blurs the image itself in object space. Use this option when you want to soften or defocus the details in a map to achieve the effect of a blurred image. Range: 0.0 to 1.0. Default=0.0.

See Blur/Blur Offset.

Filtering

Lets you choose the filtering (antialiasing) method used for the bitmap.

• Pyramidal (the default)
• Summed Area
• None

Map Channel

Assigns a map channel value to the map. Range: 1 to 99. Default=1.
