Appearance settings

What this covers

This page describes every setting in the Appearance tab of the 3D scene editor. Use this tab to control how the camera renders the scene, what the background looks like, and how the scene is lit.

Camera

These settings affect how the camera sees and renders the scene.

Camera exposure

Controls how bright or dark the final image appears. Lower values produce a darker image; higher values produce a brighter one.

This is a physical exposure value. Very small changes have a large visual effect — use the slider and watch the viewport to find the right level for your scene’s lighting.

Camera field of view

The angle, in degrees, of the camera’s horizontal field of view. Range: 1–179°.

• Smaller values (narrow FOV) produce a telephoto, compressed look.
• Larger values (wide FOV) produce a wide-angle, more expansive look.
• 50° is a common neutral starting point.

Note

Field of view has no effect when the interaction mode is set to Fixed camera, since that mode uses the FOV defined in the scene itself.

Camera bloom

A post-processing effect that causes bright areas of the scene to bleed a soft glow into surrounding pixels. Adds a cinematic quality to scenes with bright light sources or emissive materials. Disabled by default.

Background

Controls what appears behind the 3D scene.

Option	Description
Diffuse IBL	Shows the blurred, diffuse version of the environment map (HDR image). The background matches the ambient lighting.
Specular IBL	Shows the sharp, reflective version of the environment map. Matches the specular reflections in the scene.
Transparent	The background is fully transparent. Use this when embedding the scene over a colored or textured webpage background.
Color	The background is filled with a solid color of your choice.

Caution

When using Transparent background and the Show fullscreen button option is enabled, be aware that the page background will not be visible in full screen mode.

Ambient lighting

A section toggle controls whether ambient lighting is enabled at all. When disabled, the scene receives no ambient illumination from Edro 3D, relying entirely on any lights already present in the 3D scene file itself.

Ambient lighting uses Image-Based Lighting (IBL) — a technique that derives soft, omnidirectional light from an HDR environment image, producing natural-looking illumination and reflections.

Property	Description
Set up IBL / Update IBL	Opens the upload dialog for the HDR environment image. This image is also used as the background when Background is set to Diffuse IBL or Specular IBL. If no image is set, a built-in neutral HDR is used as a fallback.
Intensity	Multiplier for the ambient light strength. Higher values brighten the scene uniformly.
Color	A tint applied to the ambient light. White produces neutral illumination. Use a warmer or cooler color to shift the mood of the scene.

Directional lighting

A section toggle controls whether directional lighting is enabled. Directional lighting simulates a single distant light source — like the sun — casting parallel rays across the entire scene.

Note

If your 3D scene file already includes its own lights, the editor will display a warning: “Your scene includes lighting on its own, you can disable this light to prevent excess lighting.” In that case, consider disabling directional lighting to avoid double-lighting your scene.

Property	Description
Orientation	Two angles — Vert (elevation, raises or lowers the light above the horizon) and Hor (azimuth, rotates the light around the scene) — that control where shadows fall.
Intensity	Strength of the light in lux (lm/m²). Higher values produce brighter illumination and stronger shadows.
Color	Color of the light. White produces neutral, sunlight-like illumination. Use warmer tones for a golden-hour look or cooler tones for an overcast effect.
Shadowing	When enabled, objects cast shadows onto each other, adding depth and grounding the scene.
