calcTangents()

void calcTangents	(	void *	_vertices,
		uint16_t	_numVertices,
		bgfx::VertexLayout	_layout,
		const uint16_t *	_indices,
		uint32_t	_numIndices )

imageFlipTangentSpaceNormalY()

bool imageFlipTangentSpaceNormalY

(

bimg::ImageContainer *&

_image

)

Flip tangent-space normal map Y (tangent-space +Y / green channel via bimg unpack/pack). Preserves the container format for uncompressed sources. Compressed inputs are decoded to RGBA8 and left as RGBA8 (no lossy re-encode back to BC).
