}

Manages an HDR (RGBA16F) framebuffer for the lighting pass output before tone mapping.

Fields

fbo_handle: u64

Framebuffer object handle.

color_handle: u64

HDR color texture handle.

depth_handle: u64

Depth renderbuffer handle (shared from G-Buffer or separate).

width: u32

Current dimensions.

height: u32

allocated: bool

Whether the framebuffer has been allocated.

generation: u32

Generation counter.

bloom_handle: u64

Optional secondary color attachment for bright pixels (bloom source).

bloom_threshold: f32

Bloom threshold (pixels above this luminance go to bloom buffer).

bloom_mip_levels: u32

Number of bloom mip levels.

bloom_mips: Vec<u64>

Bloom mip chain handles.
