đ 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.
đ 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
đ 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.
