std::shared_ptr< Core::VKImage > MayaFlux::Kakshya::TextureContainer::to_image

(

uint32_t

layer = 0

)

const

Upload the pixel buffer to a new VKImage via TextureLoom.

Parameters

layer

Array layer index for array textures (default 0).

Returns

Newly created and uploaded VKImage. Null on failure.

Creates a fresh 2D texture each call. Does not cache the result. The returned image is owned by TextureLoom's internal registry.
