New Features: 

• Full PBR workflow and rendering. Supports non-destructive material editing, allowing artists to adjust textures on the fly.
• A completely new library of 152 models, ranging from seedlings to towering forest models, includes thousands of 3D surface-scanned PBR textures. Each individual model file (.spm) contains multiple polygonal resolutions and adjustable seasonal variations.
• Vastly improved export pipeline. Exports now run much faster and use far less memory. Other improvements include UDIM support, hierarchical exporting, and better bone unwrapping, weighting, and material binding.
• New leaf batching system. Leaf rendering in the SpeedTree Modeler is up to 1,000 times faster than version 7. This innovation greatly speeds the modeling process and supports the creation of more complex models.
• Major leaps in wind realism. Cinema 8 captures the complex dynamics of wind among leaves and branches more naturally than ever. The overhauled system features a realistic rolling wind effect, is much easier to tune, and includes a new wind wizard.
• Numerous other improvements. There are more than two dozen other substantial improvements including a new art director tool, an overhauled mesh cutout system, decoration and knot generators, and new bifurcation and spine noise systems.
