Sci-Fi Floor Pack: Conveyor

Unity

Overview​

Sci-Fi Floor Pack: Conveyor is a modular conveyor floor asset for Unity. It supports Straight and Rotational modes depending on movement direction, and detects Rigidbodies inside a trigger Collider to move them based on script settings.

• Modular prefabs with snap placement
• Conveyor control script (SFP_ConveyorBelt)
• Dedicated shader: rubber/steel surfaces, belt scroll, side flow Emission
• Built-in RP, URP, and HDRP via included UnityPackages

How to Purchase​

Available on the Unity Asset Store.

Included Prefabs​

Quick Start​

1. Place the desired prefab in the scene.
2. Select Conveyor_MoveZone, which is a child of the prefab.
3. Set Speed to the desired value in the SFP_ConveyorBelt component.

4. Attach a Rigidbody + Collider to the object that will move on the conveyor.
5. Press the Play button to run the scene.
   
6. The object moves along the conveyor belt.
7. If using URP or HDRP, see the URP/HDRP Upgrade section.

SFP_ConveyorBelt Script​

Continuously applies a velocity vector to Rigidbody objects inside the trigger (FixedUpdate-based). The Conveyor_MoveZone Collider must have Is Trigger = On.

Conveyor Type​

Select the conveyor operation mode and set the movement speed.

Item	Description
Shape	Select Straight or Rotational type
Speed	Movement speed and direction (negative reverses direction)

Straight (Linear Conveyor)​

Settings for linear conveyor movement along a single direction.

Item	Description
Straight Dir Local	Movement direction vector in the local coordinate system (e.g., 0,0,-1 → -Z)
Straight Lock Gain	Strength of centering (pull-in) toward the belt center. Higher values center more strongly

Rotational (Circular Conveyor)​

Settings for circular conveyor movement around a center point.

Item	Description
Center	Transform that serves as the rotation center
Inner Radius / Outer Radius	Radius range (inner/outer) where movement is applied
Clockwise	Clockwise toggle
Radial Lock Gain	Strength of centering toward the rotation path. Higher values reduce path deviation

---

Conveyor Belt Shader​

Controls belt scroll and side flow Emission. Operates independently from the physical movement (SFP_ConveyorBelt script). Adjust speeds separately for visuals.

Base Textures​

Basic texture properties. If the texture is divided into upper and lower areas, use the Belt Surface Type property to switch between them.

Item	Description
Albedo	Base color texture for the conveyor surface
Normal Map	Normal map for surface detail
Mask Map	Mask map - R: Metallic - G: Occlusion - A: Smoothness

Belt Settings​

Properties for the belt section.

Item	Description
Belt Surface Type	Switch between Rubber / Steel surfaces
Belt Scroll Speed	Scroll speed for the belt. Default is 0.5

Side Flow Settings​

Emissive effect along the side of the conveyor (decorative light strip).

Item	Description
Side Flow Emission Color	Emission color (HDR supported)
Side Flow Pattern Texture	Pattern texture. A small texture is sufficient (e.g., 256×32)
Side Flow Pattern Index	Selects one of 4 patterns stacked vertically in the texture - 1 = top, 4 = bottom
Side Flow Pattern Tiling	Pattern tiling
Side Flow Speed	Flow speed of the pattern (positive/negative to reverse direction)

URP/HDRP Upgrade​

Import the UnityPackage that matches your project’s render pipeline from the _Upgrade folder to automatically switch materials/scene settings/shaders.

• URP: SciFiFloorPack-Conveyor_URP.unitypackage
• HDRP: SciFiFloorPack-Conveyor_HDRP-12x/14x/16x/17x.unitypackage

HDRP Versions per Unity Version​

• Unity 2021.3+ → HDRP 12.x
• Unity 2022.3+ → HDRP 14.x
• Unity 2023.2+ → HDRP 16.x
• Unity 2023.3, 6000.x → HDRP 17.x
  
  Check the exact version in your project’s Package Manager.

FAQ​

Q1. Objects stop on the belt.
A. Make sure Is Trigger is enabled on the Conveyor_MoveZone Collider, and verify that the moving object has a Rigidbody.

Q2. In the rotational type, objects are pushed outward.
A. Increase Radial Lock Gain, or adjust Inner/Outer Radius. Also make sure the Center reference is correct.

Q3. The texture scroll speed looks different from the actual object movement speed.
A. Shader scroll is for visuals, while the script speed is for physics. They are independent. Match the values if necessary.
