🎁 20% discount is available to Spline Mesher users.

Effortlessly place prefabs along or inside Unity Splines, with full creative control over positioning, rotation, and scale.

Use a flexible stack-based modifier system, where each step builds on the last, and line- or area masking for extra control.

🛠 You will be able to:

• Place streetlights, utility poles, or signs along roads and pathways
• Build fences, railings, and barriers following curves
• Scatter rocks, debris, or ruins across a zone or area
• Position checkpoints, race gates, or waypoints for driving or flying games
• Spawn your visual effects like fog patches, fireflies, or magic zones
• Generate procedurally placed NPCs, enemies, or creatures along paths

🚀 And so much more! Your creativity is the limit!

This tool makes for a pivotal companion in the creation of environments, structures or certain gameplay logic. Expertly crafted for professionals - easy to use by anyone.

🌟 Features

• Distribution along the spline curve or on knots.

• Spawning within a spline's flat area

° Uniform distribution without overlaps

° Radial distribution in rings

° Grid-based in rows & columns

• Innovative stack-based modifier system

• Deleting or restricting objects with other splines (masking)

• Random selection of input prefabs using a probability %

• Jobs/Burst and GPU accellerated, responsive and lightning fast realtime changes

📑 Modifiers:

• Offset

• Rotate

• Scale (uniformly, separate axis and randomly)

• Snap to Collider

• Snap to Grid (X/Y/Z)

• Cull

• Curvature Filter (limit to curved or straight sections)

• Height Filter

• Custom

🔃 Modifiers can be reordered at will, making any specific flow of operations possible.

✅ Supports

• Runtime spawning, just modify the spline, no extra code besides yours!

• Multiple splines within the same container

🚧 Limitations:

• Cannot access terrain information. No spawning based on terrain layers.

• Spawned objects cannot remove objects from other spawners.

• Not completely suitable for 2D level design (assumed XZ axis in some cases)

❓ How is this different from Spline Mesher?

This tool places existing prefabs along splines, it does not generate curved meshes from splines.
