====== Export Material ======

Use 'File->Export material...' to save the model from the current view as a series of maps intended to be used as texture maps on another tree model.  This technique is used largely when making real-time tree models but is also useful for making simple models for background rendering.

The basic idea is to create a model of a small part of the tree that you plan to replicate.  Typically, this a section of branches and leaves which will become a leaf texture map on another tree model.  The image below shows a model and the corresponding three maps created via 'File->Export material...'.

The leftmost image is that of the tree model itself.  The three images on the right of the arrow depict the three maps generated by the tool: diffuse, normal, and specular.  Notice that texture streaking is automatically applied to the diffuse and normal maps.

The 'Window' properties have two utilities that work in conjunction with material exporting:

  - [[tree_window#Screenshot Safe Frame|Screenshot Safe Frame]]:  Shows a red border around a user controlled aspect ratio.
  - [[tree_window#Screenshot Assist|Screenshot Assist]]: Apply random HSV variation, HSV level adjustments, and normal map exaggeration to the leaves.
