======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 s texture.

=====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.


==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.
