Struct GBufferAttachment 

pub struct GBufferAttachment {
    pub semantic: GBufferSemantic,
    pub format: GBufferAttachmentFormat,
    pub color_index: u32,
    pub texture_unit: u32,
    pub clear_value: ClearValue,
    pub linear_filter: bool,
    pub mip_levels: u32,
    pub texture_handle: u64,
    pub label: String,
}

Describes a single attachment in the G-Buffer.

Fields

semantic: GBufferSemantic

Semantic role of this attachment.

format: GBufferAttachmentFormat

Pixel format.

color_index: u32

The color attachment index (for MRT). Depth attachments use index u32::MAX.

texture_unit: u32

Texture unit to bind when sampling this attachment in the lighting pass.

clear_value: ClearValue

Clear value for this attachment (RGBA or depth).

linear_filter: bool

Whether this attachment should be sampled with linear filtering.

mip_levels: u32

Mip levels (1 = no mipmaps).

texture_handle: u64

Internal texture handle (opaque ID).

label: String

Optional label for debug tooling.
