pub struct Lightmap {
pub image: Handle<Image>,
pub uv_rect: Rect,
pub bicubic_sampling: bool,
}
Expand description
A component that applies baked indirect diffuse global illumination from a lightmap.
When assigned to an entity that contains a Mesh3d
and a
MeshMaterial3d<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.
bicubic_sampling: bool
Whether bicubic sampling should be used for sampling this lightmap.
Bicubic sampling is higher quality, but slower, and may lead to light leaks.
If true, the lightmap texture’s sampler must be set to bevy_image::ImageSampler::linear
.
