Vine Generator¶

Add and draw vine to your scene. Vine Generator allows you to add vine to walls and other surfaces.

Spawn Vine Generator¶

Vine Generator is spawned using engon Asset Browser by using the engon Panel or E key. You can filter by Geometry Nodes filter. Get more information about Spawning Assets.

Draw Vine¶

You can easily create your own vine, or modify the shape of the default one, using Blender's Draw Tool. To make these changes, make sure you are in Edit Mode.

Vine Generator Properties Panel¶

To modify Vine Generator head over to Modifier Properties Panel in Blender. Make sure that the vine object is selected. Here is a quick explanation of every feature in Vine Generator.

Leaves Collection¶

Leaves Collection specifies collection for particle system used for leaves that are spawned on the stem.

Stem Material¶

Stem Material is used to change material of the stem.

Target Object and Target Collection¶

Target Object defines an object that is used as a parent of the selected vine. When the object is selected, the vine will follow the shape of the object and remain snapped to its surface. Target Collection makes it possible for the vine to be snapped to multiple objects in a selected collection. The vine will automatically snap to the closest object from the collection based on the distance between the object and the vine.

Merge Distance¶

Merge Distance is used to control the minimal distance needed for two segments of vine to connect. It also downsamples the curve object. This reduces the amount of segments per curve. To combat rough transitions in stem, make use of Curve Subdivision.

Stem Resolution¶

Stem Resolution sets the number of vertices used to generate the shape (cross-section) of the stem. Higher number of vertices means smoother stem shape but worse performance.

Curve Subdivision¶

Curve Subdivision adds subdivision to the curve object used to generate the stem, smoothing the shape and flow of the stem curve.

Stem Thickness¶

Stem Thickness modifies the thickness of the stem, specifically the radius of the stem.

Leaves Density¶

Leaves Density changes the density of leaves in percentage coverage of the stem.

Min Scale and Max Scale¶

There are two properties affecting the randomized scale of leaves. Min Scale affects the minimum scale of the leaves, Max Scale sets the maximum scale of the leaves.

Scale Leaf Towards Tip¶

Scale Leaf Towards Tip affects the scale of the leaves closer to the tip of the vine branch, simulating growth.

Cast to Target¶

Cast to Target enables or disables snapping of the vine to Target Object or Target Collection.

Target Object or Target Collection has to be set for Cast to Target to work.

Angle Threshold¶

Angle Threshold sets the maximum angle the leaves rotate when snapping to an object.

Target Object or Target Collection has to be set for Angle Threshold to work.

Normal Orientation Distance Threshold¶

Normal Orientation Distance Threshold is an option which rotates the particles around the normals of an object.

Target Object or Target Collection has to be set for Normal Orientation Distance Threshold to work.

Rotation Sky Influence and Deviation Sky influence¶

To change the influence the sky has on the rotation of individual leaves make use of these options. Rotation Sky Influence modifies the angle of leaves, rotating them towards the sky. Deviation Sky Influence slightly diverts the rotation of the leaves from the sky.

Alternate Leaves¶

Alternate Leaves is an amount from which the leaves spread away from each other so every second leaf gets rotated to a direction opposite the previous one.

Seed¶

Seed modifies the seed - spawn location, size and rotation of the leaves on the stem.
