Struct bevy_pbr::Lightmap

pub struct Lightmap {
    pub image: Handle<Image>,
    pub uv_rect: Rect,
}

A component that applies baked indirect diffuse global illumination from a lightmap.

When assigned to an entity that contains a Mesh and a StandardMaterial, if the mesh has a second UV layer (ATTRIBUTE_UV_1), then the lightmap will render using those UVs.

Fields

image: Handle<Image>

The lightmap texture.

uv_rect: Rect

The rectangle within the lightmap texture that the UVs are relative to.

The top left coordinate is the min part of the rect, and the bottom right coordinate is the max part of the rect. The rect ranges from (0, 0) to (1, 1).

This field allows lightmaps for a variety of meshes to be packed into a single atlas.
