本软件是关于SpeedTree树木植物UE4游戏引擎插件V8.1.4B4版，大小：380 MB，支持UE4软件，语言：英语。
Speedtree是一款专门的三维树木建模软件，支持大片的树木的快速建立和渲染，而且它本身还带有强大的树木库，软件是由美国IDV公司研发制作的。不仅可以通过插件将树木导入到其他的三维建模软件中使用，也可以为游戏引擎提供强大的树库支持，目前已经成为著名游戏引擎Unreal的御用树木生成软件。

SpeedTree因为它的实时几何体建模技术而在游戏行业闻名，并且因为树叶的制作而成为了电影与电视行业的主要工具。虽然这个程序对电影与广播行业来说还是个新的品牌，但这个工具在游戏行业已经是反复使用了，从而能够制作出各种丰富成熟的功能。SpeedTree被认为是电影阿凡达中不可或缺的一个工具。
工业光魔采用SpeedTree Cinema软件来制作电影《阿凡达》中潘朵拉星球上的树木场景。IDV的新版本软件SpeedTree Studio已经上市，售价895美元。
IDV已经推出了Speed Tree Studio，这是SpeedTree Cinema树木制作软件的实惠版本，价格会有所下降。新产品将这项技术的价格从4995美元降到895美元。
SpeedTree Studio有许多SpeedTree Cinema中的功能，包括用程序或是手绘来制作树木的选项，还有模拟风的效果的选项；但是缺少浮动许可证，世界的构建，直接研发支持和64-bit版本。
产品中附带了5个树木模型，但是您可以在网上从SpeedTree Model Library中购买更多的模型。
3D VEGETATION MODELING FOR UE4
Available as a subscription modeler for UE4 or a full license for UE4 Custom, the integration of SpeedTree® for Games offers a diverse range of features: a highly versatile modeling app, lightmap-ready UVs, scalable wind effects, seamless LOD and more.
FEATURE LIST
PBR Materials and Workflow- Full PBR rendering in the SpeedTree Modeler as well as new editing tools for materials allow artists to fine tune their models before exporting into UE4.19+.
New Auto-LOD- New Intelligent method of LOD generation allows incredibly quick optimizations with the press of a button.
Parent Extensions- Extend your branches into the child branch, meaning limbs naturally extend to points, rather than nubs.
Phyllotaxy Generation Algorithm- New generation algorithm based on how leaves naturally grow on branches.
Mesh Cutout System- Easily cut meshes to the shape of your leaf or cluster using our new mesh editor.
Spine Noise- New property applies late or early noise along the length of the branch or trunk.
Bifurcation Generation Algorithm- New Branch algorithm automatically adds new child branches to create natural organic branch structures incredibly quickly.
Leaf Collision- New tool to automatically remove intersecting leaves or clusters.
Knot Generator- Completely refigured geometry for knots allows for more interesting gashes, knots, and scars.
Material Sets- Materials can be grouped into sets to allow edits across multiple leaf types or bark textures.
Discrete Season Approach- One .SPM model now uses a season curve to create unique trees at any point in the year.
Faster AO Computation
Interval Generation Algorithm- New algorithm that places branches in a set interval.
Aspect Ratio Correct Mapping-Textures wrap correctly, avoiding unsightly stretched textures.
Knockout- Automatically remove interior colliding branches to simplify structure.
New Split feature- Split replaces bifurcation, offering more natural split trees with wrapped textures.
Shape Control- Extend branches to a certain diameter sphere, allowing you to create “broccoli” tree structures.
Pruning- Automatically and intelligently reduce the number of branches across the tree.
Decoration Generators- New “Fin” generator allows addition of more shelf fungus and more.
New Variance Models
Ancestor Gravity- New force applied per generator that applies gravity relative to it’s parent.
Shell Geometry- Create more interesting trunks or stumps with the new Shell Geometry generator.
Art Director Tool- Allows intuitive shaping of the tree, whether shaping entire branch levels or a single twig.
