-Each generator has the ability to adapt to Season changes by using the properties in the Seasons group (found in the Property bar on the left hand side) and by the assignment of the materials in the Leaves group. The image below shows the Material assignment and Season properties for an example model.+Each generator has the ability to adapt to Season changes by using the properties in the Seasons group (found in the Property bar on the left-hand side) and by the assignment of the materials in the Leaves group.

-Each material has a Season curve (circled in red in the picture above). The chance a material is chosen for a node is multiplied by the value of this curve at the node's "​transition value."​ So, spring leaves should have high values at the left hand side of the curve and low values at the right to indicate that they have a high chance of being chosen earlywhile having a low (even 0%) chance of being chosen late.+Each material has a Season curve (circled in red in the picture above).

 If you check the "Show Dropped Leaves"​ checkbox on the season slider, leaves that have reached the end of their lifetime on the model will be displayed on the ground. If you check the "Show Dropped Leaves"​ checkbox on the season slider, leaves that have reached the end of their lifetime on the model will be displayed on the ground.
