Game Tree Generator V1.1

Create unique, semi-realistic vegetation directly in Blender—optimized for real-time use in video games.

Game Tree Generator V1.1 combines a flexible procedural vegetation generator with a convenient game-asset workflow. Trees, bushes, and hanging plants can be viewed through a live preview, customized in detail, intelligently randomized, optimized, and exported as ready-to-use assets for Unity and other game engines.

Included vegetation

Create a wide range of vegetation types, including:

• Oak

• Maple

• Beech

• Birch

• Apple tree

• Pear tree

• Fir

• Spruce

• Juniper

• Elder

• Rhododendron

• Various bushes

• Hanging ivy and trailing plants

Flexible procedural design

Customize the most important characteristics of every generated plant:

• Overall height with proportional scaling of related parameters

• Trunk thickness, curvature, and geometry detail

• Branch count and branching levels

• Branch length, radius, direction, and distribution

• Crown shape and canopy volume

• Foliage density and cluster size

• Leaf-plane angle, rotation, and random orientation

• Volumetric foliage clusters designed to create more volume with fewer planes

• Surface roots that can partially enter and reappear from the ground

• Different age stages

• Young, mature, old, and dead trees

• Seasonal variations such as summer and autumn foliage

The intelligent randomizer creates believable variations based on the selected species. This allows you to generate multiple examples of the same plant without producing obvious duplicates.

Optimized for mobile, PC, and console

Different performance profiles adapt the generated vegetation to the intended target platform. Mobile settings reduce geometry and foliage complexity, while PC and console profiles provide additional detail for closer viewing distances.

Performance-oriented features include:

• Automatically generated LOD stages

• Earlier LOD transitions for mobile devices

• Billboard representation for long viewing distances

• Efficient alpha-clipped materials

• Foliage-only bushes without visible branch geometry

• Optimized foliage clusters for greater canopy volume

• Shared texture atlases for plants of the same species

• Ground-aligned pivots for reliable placement inside a game engine

Bushes and hanging plants

Bushes are not simply scaled-down trees. They use dedicated growth proportions, broader lower shapes, shorter branches, and specialized controls for spread, density, and branch thickness.

For especially lightweight background vegetation, bushes can also be generated as foliage-only assets.

Hanging-ivy presets allow you to create trailing plants, individual vines, and dense foliage curtains. Width, drop height, vine count, side shoots, wall distance, curvature, and foliage density can all be adjusted.

Realistic materials and textures

The add-on includes different materials and textures for:

• Bark variations

• Deciduous foliage

• Coniferous foliage

• Bushes

• Ivy and hanging plants

Organic alpha masks cut the leaf planes into more natural silhouettes and reduce visible rectangular edges. The included textures are designed around a semi-realistic, subtly hand-painted game-art style.

Unity URP wind

During export, the add-on can automatically prepare the generated vegetation for the included Unity URP wind shader.

The wind system is designed to move:

• The trunk only slightly

• Branches with moderate movement

• Leaves and smaller twigs more noticeably

• Roots and the lower trunk as little as possible

Wind strength, speed, and movement intensity can be adjusted directly in Unity. This shader-based solution is significantly more efficient than complex skeletal animation, making it especially suitable for mobile games.

Game-ready export

The integrated export workflow can generate:

• An FBX model

• Transparent BaseColor textures

• Baked texture atlases

• Unity URP materials

• Multiple LOD stages

• A distant billboard

• Wind shader support and wind data

• Automatically configured Unity prefabs

• English asset names based on the selected plant species

Multiple plants of the same species can reference the same exported atlas. For example, four different oak trees do not require four duplicate copies of the same texture set.

Generated assets are automatically aligned to ground level and can be placed directly into a game scene after import.

Ideal for

• Mobile games

• PC and console games

• Urban environments

• Gardens and parks

• Street vegetation

• Forests and natural landscapes

• Background vegetation

• Stylized and semi-realistic projects

Game Tree Generator V1.1 turns the usually time-consuming process of modeling, variation, optimization, LOD creation, texturing, and engine setup into one accessible workflow—from live preview to a finished game asset.
