Simple Tree Tools 2.7 - A complete set of fully procedural tree modeling tools for Houdini. Simple and intuitive to use, yet advanced enough for creating any kind of procedural tree or foliage. All the features needed for realistic tree creation is here. Everything from simple bending to more advanced features like 4 types of Tropisms and Real Time Wind and Growth animation. There are also tools included aimed for game developer workflows.

Tools:

• Trunk Maker: Create simple trunk with a few controls for shape. You can even use multiple curves as input or optional Seed Points and grow trees from there.

• Branch Maker: Create branches from any previous level, you can pipe as many levels as you want after one another. 

• Simple Leaf: As it sounds, simple leaf creation tool with a few controls.

• Leaf Scatter: Very powerful scatter tool for leaves. Scatter leaves (or any geometry) on any previous levels of your choosing. It also has simple "wind animation" and random color and distribution options.

• Deintersect: Deintersect scattered leaves.

• Leaves From Branches: Build leaves from curves input. Useful when creating flowers or other foliage when scattering leaves instances isn't enough.

• Geo to Branches: Deform custom geo along the tree curves with distribution options. Can be used with scanned geo or simple planes with textures for example.

• Tree Mesher: Mesh your tree with intuitive controls. It also has advanced controls for "trunk flares", building knots and custom cross-sections.

• Seams Maker: Create seamless transitions where the branches intersect with normal and uv blending.

• Wind Modifier: Beautiful detailed wind animation on anything from small plants to big trees.

• Simple Motion: Animate the tree curves with Simple Motion. Natural looking Realtime Wind simulation. Even on big trees with a lot of branches!

• Simple Leaf Motion: Create simple leaf rustle. Very fast and works on packed geo. This means you can animate an entire field of grass for example.

• Simple Grow: Grow your trees or plants with this node.

• Simple Bone Deform: Deforms "Tree Mesher" and "Leaf Scatter" after animation.

• Atlas Processor: Create leaves or branches geometry from stencil maps with a lot of options for polycount and shaping.

• STT to PivotPainter: A "Bridge" tool to be used in conjunction with Labs Pivot Painter tool. It makes all the necessary attributes and pivots from a Simple Tree Tools tree.

• Initialize Curves: Take any input curve and make it work with the rest of the STT system.

• Inject Curves: Inject curves into an already built system.

• Falloff: System wide unified falloff node with a lot of options.
