======Map Editor======

The Map Editor is the dialog presented when you click the texture buttons on the [[toolmaterialsassetsbar|Material Asset Bar]].

The controls at the top of the dialog allow you to browse for a texture, reload a texture, or remove a texture.

=====Map source=====

Map sources can be image files, color gradients, or noise patterns.

^ **Property** ^ **Description** ^^
|**File**|Load an image file as the map.|| 
|:::|**Recolor**| Change the map colors with the [[toolcolor_editor|Color Editor]]. The [[toolcurve_editor|curve]] sets the color distribution. The slider sets the amount of recoloring. |
|**Linear gradient**| Use a linear gradient color pattern for the map.||
|:::|**Center** | Move the center position of the gradient along the x- or y-axis. |
|:::|**Distance**| Set the size of the transition between colors. |
|:::|**Angle**| Set the rotation of the gradient. At a value of 90, gradients run from bottom to top. At 0, gradients run from left to right. |
|:::|**Color**| Set the minimum and maximum colors with the Color Editor. The curve sets the color distribution. |
|**Radial gradient**| Use a radial gradient color pattern for the map.||
|:::|**Center**| Set the center position of the gradient. With both values at 0.5, the gradient is exactly centered. |
|:::|**Distance** | Set the size of the transition between colors. |
|:::|**Color**|Set the minimum and maximum colors with the Color Editor. The curve sets the color distribution. |
|**Noise**| Use a noise pattern for the map.||
|:::|**Center**| Set the start location of the noise pattern in UV space. |
|:::|**Scale**| Change the size of the noise pattern. This property affects the frequency of perturbations.|
|:::|**Seed**| Change the seed distribution. Use this property to line up multiple noise maps.|
|:::|**Color**| Set the minimum and maximum colors with the Color Editor. The curve sets the color distribution. |

=====Adjustments=====

All adjustments can be done in real-time. Any adjustments made to the loaded textures will be baked in when the tree is exported.

^^**Property**^**Description**^
|**Channel**|This option is available only for grayscale maps, such as Opacity or Gloss. A texture file may have multiple channels: red, green, blue, and possibly alpha. This option lets you choose which channel to use for this map. Luminance, which is the grayscale version of RGB, is also an option.|
|**sRGB to Linear**|All rendering in the SpeedTree Modeler is done in linear space. That is, with no gamma adjustment applied. Enabling this option converts a texture from sRGB (the most common image gamma) into linear space for rendering. If your texture is already in linear space (which is rare), then disable this option.|
|**Normalize**|This option is available only for grayscale maps, such as Opacity or Gloss. Normalize will rescale the texture data so that it uses the entire black to white range.|
|**Invert**|This inverts the texture. White becomes black, and vice-versa.|
|**Invert RGB**|These options let you invert individual channels of your texture. This is very useful on normal maps, which may be in a different space than the Modeler expects. For instance, normal maps with a flipped green channel are pretty common.|
|**Brightness**|This option makes the texture brighter or darker.|
|**Contrast**|This option can increase or decrease the contrast (the difference between the light and dark parts) of the texture.| 
|**Saturation**|This option can increase or decrease the saturation of the texture, which is how "colorful" the texture appears.|
|**Red**|This option modifies the texture to be more or less red.|
|**Green**|This option modifies the texture to be more or less green.|
|**Blue**|This option modifies the texture to be more or less blue.|
|**Minimum**|Adjusting the minimum, along with the maximum, allows you to rescale the texture luminance into a certain range. This is especially useful when bringing the color map into the right range for PBR rendering.|
|**Maximum**|Adjusting the maximum, along with the minimum, allows you to rescale the texture luminance into a certain range. This is especially useful when bringing the color map into the right range for PBR rendering.|
