Cameras, lighting and environment

Prerequisites: a writable project with visible geometry. Stop Play while preparing the scene.

Prepare the game camera

Position the editor view using the viewport controls.
In Project → Scene → + Add, choose Camera. New cameras use the editor-view placement.
Select the camera, choose Align to editor view if needed, then inspect its Transform. Game cameras look along local +Z.
In Camera, enable Active, set Priority, Zoom, projection and clipping planes. The highest active priority determines the game camera.
Save and press Play to inspect the runtime view.

Expected result: Play uses the active scene camera rather than the authoring camera. Optical zoom above 1 magnifies; values below 1 zoom out. Use the current-camera API for scripted selection rather than assuming editor selection changes the runtime camera.

Add a light

Choose + Add → Light, then select it.
In Inspector's Light section, choose Directional, Point or Spot.
Set Light color and Intensity; adjust Range for point/spot lights and Cone half-angle (degrees) for spot lights.
Position/rotate the entity. Directional and spot lights shine along local +Z. Save and inspect Play.

Expected result: geometry responds to the light configuration. Intensity 0 turns a light off. The current renderer supports up to 32 scene lights and does not implement shadow casting yet.

Set sky and atmosphere

Expand Scene sky & atmosphere in Inspector and enable the scene environment.
For an image sky, first copy a 2:1 panorama into the project. Use Choose image… for HDR, PNG, JPEG or TGA; external files are rejected.
Adjust sky rotation/exposure, ambient color/intensity, sun color/intensity/direction and haze color/density/start.
Use Clear image for a solid sky or Reset environment to restore defaults, then save.

Expected result: preview and Play use the scene environment. Environment sun settings and scene light entities are separate controls; a panorama does not imply full image-based lighting or a browser UI renderer.
