Procedural Vines - Troubleshooting and support

Focused checks

Swipe the table to read every column.

Symptom	Check
Regenerate finishes with no strands	Check Seed Count / Extra Seeds, actor origin outside the visible side face, trace distance and blocking collision. A floor-like initial anchor or exclusion containing the root can reject generation.
Stems stop before Max Length	A strand may reach an unsupported edge, exclusion or branch-length limit. Review the supporting collision and Step Distance; Max Length is a budget, not a guaranteed length.
Shape changes when moved	The actor samples a different surface and world-space exclusions. A fixed seed does not freeze the environment.
Surface Offset does not move the stem away	Stem clearance uses its radius, root flare and radius noise. Surface Offset primarily affects foliage attachment.
Changing Leaf Size Range has little effect	Check whether Leaf Variation Meshes or Leaf Static Mesh is active. Use Leaf Instance Scale for instanced mesh size.
Single leaf mesh appears ignored	Any valid Leaf Variation Meshes entry takes precedence. Clear that array to use Leaf Static Mesh.
Leaf or stem tint does not show	Procedural tint is stored in vertex colors. The material must read it. Instanced leaves use mesh/material color, not the procedural quad tint.
Leaves appear near an opening	Check valid world bounds and depth, then regenerate. Exclusion boxes are per vine actor and remain fixed when actors move.
Is Generating never settles during edits	Stop issuing repeated Regenerate requests or moving the actor. Each new request cancels the current job.
Climbing cannot start	Use a Character owner, face blocking simple collision, check Detection Reach, trace channel and surface-normal thresholds. Leaves have no collision.
Character climbs unrelated walls	The component accepts blocking geometry. Restrict Climb Trace Channel and target collision responses.
Character keeps moving after releasing input	Send Set Climb Input(0, 0) on input completion/cancellation. Stored values persist until changed or climbing stops.
Climbing catches at an edge	Inspect capsule size, supporting simple collision, Reattach Distance and mantle clearance. Supply your own animation/IK and validate the movement against your geometry.

For a reproducible report, include engine and plugin versions, the relevant actor/component settings, seed, target collision setup, expected result and a screenshot or short recording. Remove private data from logs before sharing.

Symptom

Check

Regenerate finishes with no strands

Check Seed Count / Extra Seeds, actor origin outside the visible side face, trace distance and blocking collision. A floor-like initial anchor or exclusion containing the root can reject generation.

Stems stop before Max Length

A strand may reach an unsupported edge, exclusion or branch-length limit. Review the supporting collision and Step Distance; Max Length is a budget, not a guaranteed length.

Shape changes when moved

The actor samples a different surface and world-space exclusions. A fixed seed does not freeze the environment.

Surface Offset does not move the stem away

Stem clearance uses its radius, root flare and radius noise. Surface Offset primarily affects foliage attachment.

Changing Leaf Size Range has little effect

Check whether Leaf Variation Meshes or Leaf Static Mesh is active. Use Leaf Instance Scale for instanced mesh size.

Single leaf mesh appears ignored

Any valid Leaf Variation Meshes entry takes precedence. Clear that array to use Leaf Static Mesh.

Leaf or stem tint does not show

Procedural tint is stored in vertex colors. The material must read it. Instanced leaves use mesh/material color, not the procedural quad tint.

Leaves appear near an opening

Check valid world bounds and depth, then regenerate. Exclusion boxes are per vine actor and remain fixed when actors move.

Is Generating never settles during edits

Stop issuing repeated Regenerate requests or moving the actor. Each new request cancels the current job.

Climbing cannot start

Use a Character owner, face blocking simple collision, check Detection Reach, trace channel and surface-normal thresholds. Leaves have no collision.

Character climbs unrelated walls

The component accepts blocking geometry. Restrict Climb Trace Channel and target collision responses.

Character keeps moving after releasing input

Send Set Climb Input(0, 0) on input completion/cancellation. Stored values persist until changed or climbing stops.

Climbing catches at an edge

Inspect capsule size, supporting simple collision, Reattach Distance and mantle clearance. Supply your own animation/IK and validate the movement against your geometry.
