The library offers a large variety of trees (some of which I have never used). I wanted the CGA rule to create trees for my shapes at random, from a specified selection. A small alteration to the CGA code changes the default value.
For this example I used the Plant_Loader_with_LumenRT_Models.cga
The Plant_Loader_with_LumenRT_Models.cga uses the Name attribute to determine the file path of the model. The "Alder Buckthorn" model is used as a default. As seen below.
By changing the Name attribute to a conditional attribute, and setting a probability for specified plant models, the CGA rule will automatically assign models to shapes. In the example below, only 20 tree models were specified with a propablity of 5% each.
The resulting rule only assigns the models that were specified as a default. Keeping the original @Range annotation in order to still be able to select any of the other available models.
