+ | ====== Upgrading Old Models ====== | ||
+ | Models created prior to SpeedTree 8 comprise mostly Spine and Leaf generators. | ||
+ | |||
+ | Please see the sections below for why you should consider upgrading old models and how to go about it. | ||
+ | |||
+ | > **Note**: | ||
+ | |||
+ | ===== Why Should I Upgrade Leaf Generators? ===== | ||
+ | |||
+ | Leaf generators have been superseded by two new generators: Batched Leaf and Leaf Mesh. The two new leaf generators are identical in their properties but differ in how they are computed. | ||
+ | |||
+ | Here's some of what you gain when you upgrade: | ||
+ | |||
+ | * Significantly faster leaf computation (up to 1000 times faster than v7 models) | ||
+ | * Easier leaf orientation | ||
+ | * Leaf deformation (fold, curl, noise) | ||
+ | * [[Resolution|Resolution]] control | ||
+ | * Improved [[leaf_collision|collision]] (leaf-leaf and leaf-branch) | ||
+ | * New season system | ||
+ | |||
+ | ===== Why Should I Upgrade Spine Generators? ===== | ||
+ | |||
+ | Three generators now do the job of the Spine generator: Branch, Frond, and Cap. The new approach requires an explicit entry in the Generation Editor for each type of geometry you want to appear. Frond and Cap generators must be the child of a Branch generator in order to work. | ||
+ | |||
+ | Here's some of what you gain when you upgrade: | ||
+ | |||
+ | * Branch extensions (child branches " | ||
+ | * Spine noise | ||
+ | * Context sensitive pruning | ||
+ | * Aspect ratio correct UV mapping | ||
+ | * Shape control | ||
+ | * Improved welding | ||
+ | * Blending between different branch materials | ||
+ | * New vertex displacement (noise, shape, flares) | ||
+ | * [[Resolution|Resolution]] control | ||
+ | * Easier control over caps and fronds | ||
+ | |||
+ | ===== How Do I Upgrade a Model? ===== | ||
+ | |||
+ | Open any old model and look at the tool bar in the Generation Editor. | ||
+ | |||
+ | It is possible to convert the entire model at once; however, it is not recommended. |
