Public Attributes
xiiSizeU16	m_AtlasSize = xiiSizeU16(2048, 2048)
	Shared extent of all four prepacked channel images (up to 16384 per axis).
xiiUInt8	m_uiPadding = 2U
	Tool packing configuration retained as metadata.
bool	m_bGenerateMipMaps = true
	Requires a complete authored mip chain when true, otherwise a single mip.
xiiDynamicArray< xiiDecalAtlasEntry >	m_Entries
	Unique decal IDs and their already resolved rectangles. No runtime packing.
xiiImage	m_LayerImages [4]
	Albedo (sRGB), tangent normal, roughness/metallic/AO (linear), emissive.

Detailed Description

Prepacked atlas produced by tools. All four channels share each entry's UV rectangle, dimensions and mip count. Images are upload data, released by the resource after GPU creation; source texture handles on entries are metadata.

Failure leaves this descriptor unchanged. Removed metadata-only atlas files require retransformation; they never contained renderable source pixels.
