Speed tree
You can construct tree procedurally to make an advantage of generators randomization
Shortcut
F / Ctrl + F - hide
H - hide
Edit modes
- Generator - edit all instances
- Node - edit single branch “Clear Node Edits” option in the menu when you right-click a generator in the
Parameters
- [+-] - Variance. help with seed randomization
- [green curve] - Parent curve. Along length of parent from bottom to end.
- [blue curve] - Profile curve. How it behave along spline. From 0 to param value.
- % of parent - Use % of parent to be procedural (can growth) «« ?!!!!!!! Shared parameters
Parameters

|---|---|---|---|
| Gen | Number of points , Spawn points placement spline | Global scale, Z-depth, Prune | |
| Spine | Length, Orientation , Start Angle, Noise | ||

Placement Mode
| mode | Count | Placement | Placement | ORIENT | Usage |
|---|---|---|---|---|---|
| Absolut | 1 | Number | Random | Random | Stomps and trunk |
| Absolut step | * | Number | Even | ||
| Proportional | 1 | Number | Random | Flat | Adapts to the size of the parent. Suitable for randomization and cases where parents are of varying sizes. |
| Proportional Step | * | Number | Even | Flat | |
| Interval | * | Distance | Even | Star | Constant frequency, adaptive number. - more for longer |
| Phylotaxy | Primarily used w high detail vfx targeted Based on botanical classifications. | ||||
| Opposite (distichous) | 2 | Distance | Even | Flat | |
| Opposite (decussate) | 2 | Distance | Even | Cross | |
| Opposite | 2 | Distance | Even | Random | |
| Whorled | * | Distance | Even | Star | |
| Alternating (distichous) | 1 | Distance | Even | Flat | |
| Alternating | 1 | Distance | Even | Random | |
| Bifurcation | Unpredictable | Random | On Curvature | Best places to produce organic structures. Natural junctions of the parent branch | |
| Flood | Number | Random | Random | Create targets or meshes attached to mesh generator or fill a general area at random. | |
| Parent | Anchors | Anchors | Random | Spawn on anchors | |
Align style
| When “Align” is enabled, generated nodes attempt to roll their initial orientation skyward as much as they can, according to the following options: | |
|---|---|
| Individual | Each node rolls skyward independently. |
| Group | All of the nodes in the group roll skyward together. |
Spine
Orientation
- start angle
- roll
- gravity / zig zag
- noise
- break
Orientation
For leaf generator
Orient
- Sky influence - rotate toward sky deform
- deform leaf mesh
- vertex control - noise
Skin
UV
Mat
Segments
Optimization / Mesh Density. Can optimize along spline with blue curve.
Length Radial
Node
Branch
- Branch
- Trunk
- Little branches
- Twigs
- Shell - divide trunk to 2 and blend materials
Leaves
- Batch leaf - packed instances
- Mesh leaf - access to each leaf
- Fond - aspect ration depend on texture aspect ratio
You can add one of leaves generators and open: Edit Cutout editor. You should add pivot, direction and plane mesh
Material
Clusters
Planes with leaf clumps
Bake billboard
- Change view from perspective to orthographic (LMB on left upper corner of viewer) or add camera ()
- Window properties > Set screenshot safe frame > set resolution
- Lighting preset > set for overcast then increases ambient light and bake AO
- File > export image > same width and height as in prev. streak colors for padding, and uncheck ground. Add imagfes channels and bake Tip: to much collisions may look like solid from distance
Features
Forces
Just add force. Select generators for which you want use the force and enable
Direction
- Magnet
- Direction
- Planar
- Return - gradual undo of forces like gravity
Rot - Gnali - rot on horizontal axis
- Twist - on y axis
- Curl - Other
- Mesh - (growth on object) can attract or repel - (need to enable collision)
- obstruct - push
- prune - delete and cut
- stop - stop growth
Free Hand
Hand drawn
Space + LMB - create
Hand drawing
Old
Shape control
- Shape control style by sphere or mesh (add mesh force enable it and then change to mesh )
Photogrammetry
- add geo > photo branch generator
- space bar and RMB
Collision
On toolbar
- low - will remove intersect other on same level
- medium - will remove intersection with parent
- high -
Material / Wind
Projectors
- Vertex Editing - minor vertex change
- Bending - without
- Click Place - clone
- Hand Drawing - <<< !!!! (space)
- Paint Displacement - move
- Paint Vert - move
- Paint Vert Col - color
