CenterScale (Material stage keyword)

Description

The centerScale keyword instructs Doom 3 to scale the texture in U and V dimensions using the specified factors. This keyword differs from the scale keyword in that it scales from the center as opposed to a corner.

The numbers given are the opposite of what might be expected - scaling by 2 causes the texture to be made smaller by a factor of 2, rather than bigger. In this sense the values could be considered “tiling” factors rather than scaling factors.

Usage

centerScale [U], [V]

Parameters

• [U] - A floating point value that determines the texture scale on the U axis.
• [V] - A floating point value that determines the texture scale on the V axis.

Example

Tile a texture into a 2-by-2 grid relative to its original size.

{
  blend diffusemap
  map textures/path/to/image.tga
  centerScale 2, 2
}

Stretch a texture to ten times its original size (probably not a good idea).

{
  blend diffusemap
  map textures/path/to/image.tga
  centerScale 0.1, 0.1
}

Notes

None.
