How to use Unity Sprite Packer for Tight & Full Rect sprites at the same time?

    I'm using Unity's sprite packer, and I need one atlas to use the default packer policy (full rect) and the rest of my atlases to use the tight packer policy. Changing the built in setting appears to apply the setting to all atlases. How can I specify this per atlas?

    Thanks!

    PS -- the reason I need one of my atlases to use the default/full rect policy is because NGUI doesn't seem to like Unity sprites that are tightly packed.

    Is this possible to do by writing a new packer policy?

    11 months later, this exact same question is still relevant. I guess it is not possible, but it is rather unclear since it is only through how GUI for the Sprite Packer works that it is evident that all atlases must use the same packing policy.

    I would also like to have multiple policies. No updates huh.

    Hi

    It is possible to write your own packing policy

    http://docs.unity3d.com/Manual/SpritePacker.html

    However, the limitation still applies that a single policy applies to atlases.

    The work around would be by checking the texture importer's tag during packing and switch to different 'sub policies'.
