Create and edit procedural vines
Create procedural vines with typical shapes and behaviors.
To make manual edits, refer to Place and edit vines manually.
Create procedural vines
To create procedural vines:
Add a Vine generator with one of the following methods:
- Add a Vine generator to a parent generator.
- Ray cast vines onto the model with a Projector scene object.
Grow vines from a Zone generator.
Added to a parent generator Cast with a Projector Added with a Zone generator 
Create a geometry force from the generators or mesh assets you want the vine to interact with.
- Enable the geometry force in the Vine generator properties. >[!NOTE] >The Vine generator must be in a later pass than the generators that make the geometry force.
Adjust the Vine generator properties to get the desired placement and shape.
Tip
Increase the Segments:Accuracy to get more detail on the vine and better collisions.
Tip
You may find it easier to position the vines over other geometry if you set the Spine:Droop:Style to Off. Once you have a desired position, set Spine:Droop:Style to On to test how the vines fall with gravity.
Common behaviors for vines
To create common vine behaviors, use the following properties:
| Vine behavior | Properties to edit |
|---|---|
| Swooping and hanging with gravity | Spine:Droop properties |
| Crawling and wrapping around other geometry | Geometry Force Crawling properties |
| Swooping in-line with a parent branch | Refer to Create low-poly vines for games |
| Following another vine or branch | Refer to Create vines that follow a guide |
