Your first environment — 2D Parallax Pro

Create one environment, add a few uniquely named layers and verify their motion before enabling atmosphere.

Create the environment#

Choose Tools > ERAGANX > 2D Parallax > Create Environment.
The Parallax Environment root has Parallax2DManager and Parallax2DCameraAdapter; the Control Panel opens.
Confirm the Environment reference, then assign Main Camera in Camera > Target Camera.
To edit an existing setup, select/assign its Manager. Create Environment again creates another root.
Save. An empty Layers list is expected before artwork is added.

Read the panel#

Section	Purpose
Environment	Manager being edited; choose carefully with multiple environments.
Camera	Rendered camera and sampled-motion smoothing.
Background Motion	Camera-driven, automatic drift or both.
Layers	New Layer Sprite, + Background / + Foreground and selected-layer settings.
Feature checkbox	Enable feature/connect required components and references; disabling retains settings.
Settings foldout	Collapse without stopping the enabled feature.
Advanced	Additional controls for that section, not a global mode.
Add Another	Independent Fog, Clouds, Rays or Particles object.

Add/remove layers and create effects in Edit Mode. Ordinary runtime Inspector changes are lost after Play Mode.

A simple scene structure#

TEXT

Main Camera
Parallax Environment [Manager + Camera Adapter]
  Hills / Trees / Bushes [SpriteRenderer + Layer]
  Atmosphere [optional Camera Anchor]
    Fog / Rays / Particles
Player + Ground [your gameplay and physics]

Your first parallax exercise#

Set camera Orthographic, Size 5, position (0,0,-10), rotation zero, and assign it.
Add Distant Hills, Far Trees and Near Bushes as Backgrounds; add Foreground Leaves as Foreground.
Use the factor/order recipe, and scale/position artwork to cover the view.
Enable Horizontal looping only for tileable artwork.
Choose Camera Driven, leave optional effects off, save and enter Play Mode.
Move camera X slowly from 0 to 10, or use GuideCameraMove. Distant layers should move less on screen; foreground passes faster.

Stop Play Mode and save authored settings. Disable the test movement helper before using your production follow controller. Keep collisions/player controls outside generated tile artwork.
