Lighting & Theme Presets

​

Overview

Lighting — the overall illumination of the 3D scene, shadows, and the environment map — is not configured in the Creator App. Instead, it is part of the scene itself, chosen when the scene is prepared in Scene Manager. The Creator App loads whatever lighting the selected scene defines and uses it for the entire training. This keeps authoring focused on training logic (states, events, actions) and keeps the visual quality of the scene consistent across every step.

​

Why Lighting Is Not in the Creator App

A training always runs inside a scene — the 3D environment the learner sees. Lighting is a property of the environment:

• Two trainings that share a scene should look the same, with the same light direction, shadows, and mood.
• A single scene used by many trainings should not have its lighting changed each time a new training is authored.
• Lighting choices affect performance (shadow quality, environment map resolution) and belong to the scene administrator rather than the training author.

For these reasons, lighting is managed centrally — in Scene Manager — and the Creator App consumes the result.

​

Available Presets

The platform ships three shared lighting presets: Each preset sets the ambient light intensity, the direction and strength of the key light, soft-shadow quality, and the environment map (HDRI) used for reflections and image-based lighting. To change a training’s lighting, change the scene’s lighting in Scene Manager. The Creator App will pick up the new lighting the next time you reload the training.

​

Performance / Shadow Quality

Scene Manager also exposes performance-related settings that affect how the lighting is rendered: These settings are stored in the scene. The Creator App honours the saved values (specifically shadows enabled and shadow quality — the shadow map resolution) when it renders the 3D viewer, so authoring previews reflect what the learner will see at runtime.

​

What the Creator App Does With Lighting

When you open a training, the Creator App:

1. Loads the scene definition.
2. Reads the scene’s lightingEnv (the preset id and render settings).
3. Applies the preset in the 3D viewer — ambient light, directional light, HDRI environment, and soft shadows.
4. Scales the light intensities slightly based on the Creator App’s own UI light / dark theme so dark-mode authoring does not wash out the scene.

Authors do not need to take any action. The viewer simply looks like the scene looks.

​

Can I Override Lighting for One Training?

Not from the Creator App. Lighting is per-scene, not per-training. If two trainings need different lighting, they should use different scenes. If you need a quick variation, ask a scene administrator to make a copy of the scene with the lighting change and point your training at the copy.
