Supported LightComponents:

PointLights, SpotLights, RectLights and DirectionalLights are supported, with Stationary or Movable mobility.

Stationary lights still support baked shadows while working with this plugin.

The LightComponents are identified by their name and must be part of the same Actor as the VideoAmbientLightComponent.

Material compatibility:

The simplest possible material would just contain the MediaTexture of your MediaPlayer connected to the emissive color output of an unlit material.

The plugin calculates the light colors based on the emissive color output of the assigned SourceMaterial. This allows for any effects added in the material to be taken into account for determining the output colors.

Performance

The performance cost of this solution is generally small and scalable so it is suitable for games with tight performance constraints. The plugin is also built to support the DetailMode system, so if your project supports different graphics quality settings, you could disable the ambient lighting completely on low settings.
