SpeedTree Cinema delivers a unique procedural plus hand modeling approach that lets you create exactly the tree or plant you want faster than ever before. Start with our large species library (all of which is yours with a Cinema license) or create your own using custom leaf or branch models and textures. Export as a mesh with baked-in wind animation via point cache, and then bring it into your rendering package of choice. SpeedTree Cinema is available in 32- and 64-bit versions available for Windows, and for the first time, Mac and Linux. It easily integrates with digital content creation/special effects software, including Maya®, Houdini, Cinema 4D, 3ds Max®, Rhino, and more.
