Tree Properties

 

In this rollout we may adjust the tree properties and other general parameters.

Width

This value defines the width of the trees. This parameter is linked with the distribution map, so if the width increments, it's possible that the distribution map's increments automatically also. The reason is to maintain a top limit for the the density of trees (see distribution map's parameters for details).

Height

Height of trees (in scene's units).  

Geometry

The trees, by default, are created as rectangular planar objects witrh a tree texture and an opacity map. If we see them from a front view, they have the aspect of tree required, but they look deformed from other viewpoint. This is corrected using the options of camera rollout (see this section for details) o also we may create them with two perpendicular planes ('Two Planes' option). With two planes, the 3D effect is maintained more accured from all viewpoints (without using the camera rollout) and also is useful for creating a more compact shadow.

Also, we can use custom meshes for trees. Select it with the 'Pick' button of this rollout. We must be care using only low face models, because the total number of faces of Forest object is equal to the number of faces of this model multiplied by total of trees.

By default, all trees have the same size of the custom mesh model, but if we enable the 'Ignore mesh dimensions' checkbox, they will have the size defined in Widht and Height parameters.

Icon Size

When the plugin object cannot create trees (because have not been defined all the required parameters), it built a icon with a 'F' sign inside. This parameter defines the size of the icon.

Random Seed

This is a any numeric value used to initialize the random number generator. This number affects to the random transforms of material, position, scale, etc. when they are used (see transform and material rollouts). For a same value, the trees always have the same transformations.
