Texture Mapping Quick Ref

This chart summarizes the characteristics of each of the Animation:Master texture maps. The background column describes how the background of the image is interpreted, the Alpha Channel column describes how the alpha channel is used and the Value/Percent column gives the use and useful range for the Value (version 8.x) or Percent (version 9.x) property.

Type	Background	Alpha Channel	Value/Percent
Color	Color rendered as is.	black=transparent, white=opaque	controls transparency of decal. 0-100%
Bump	Use gray. Change in gray value=slope. dark on light=concave, light on dark=convex	Not generally used.	scales effect. negative values reverse direction of effect. -1000 to 1000%
Transparency	Use gray. gray value controls transparency. black=transparent, white=opaque	Not generally used.	scales effect. 0 to 1000%
Specular Size	Use gray. gray value controls size of specular highlight. black=no highlight, white=larger highlight	Not generally used.	scales effect. 0 to 1000%
Specular Intensity	Use gray. gray value controls specular brightness. black=no highlight, white=brighter highlight	Not generally used.	scales effect. 0 to 1000%
Diffuse	Use gray. gray value controls darkening. black=darkens to black, white=no darkening	Not generally used.	scales effect. Negative values brighten. -1000 to 1000%
Reflectivity	Use gray. gray value controls reflection. black=no reflection, white=mirror	Not generally used.	scales effect. 0 to 1000%
Ambiance	Use gray. gray value controls ambiance (self illumination). black=no ambiance, white=100% ambiance.	Not generally used.	scales effect. Negative values remove light. -1000 to 1000%
Cookie Cut	Color rendered as is except if a key color is specified. Key color is rendered as transparent.	controls transparency of model (not decal). black=transparent, white=opaque	controls how color is rendered. negative values invert colors. Magnitude is brightness. -1000 to 1000
Displacement	Use 256 level gray. gray value controls displacement from orginal surface. 0=-127 cm, 255=127 cm. Renders smooth transitions	scales effect from 0 (black) to 100% (white)	scales effect. Negative values reverse direction of displacement. Keep values small.
Fractal	Use 256 level gray. gray value controls displacement from orginal surface. 0=-127 cm, 255=127 cm. Renders polygonal transitions	scales effect from 0 (black) to 100% (white)	scales effect. Negative values reverse direction of displacement. Keep values small.
