the memory is used almost doubled. Because of the metadata!

    Hi,

    When you say there’s an increase in memory usage – are you referring to a temporary cost of moving data around when the MIP-Map levels aren’t aligned? This is going to happen with NPOT textures as well, so the Meta Data alignment won’t solve it for everyone.

    FYI, the 15bytes of meta data are from the axis alignment of the texture. If you uncheck “vertical flip” when compressing your texture (and there’s not already meta data in the image) then no meta data will be added. That option adds the meta data to indicate that it should be effectively displayed upside-down.

    We’re working on a new version of the SDK tools as well – this will solve the issue by allocating the texture memory into a separate buffer to the meta data, allowing alignment to occur naturally.

    Thanks,
    Tobias
