    Try using the Blender preset in the OBJ Importer, Blender (like 3D Studio) has the Z axis pointing up and the y axis pointing forwards while DS (like many applications) does the opposite.

    There are a couple of ways to cure that, in Blender, rotate -90 degrees around the X axis, or deal with the issue in the obj import window in DS by re-assigning the axes where Z maps onto Y and Y onto -Z.

    There is also one additional thing to be aware of. Unless you import as DS 100% scale, the object is moved so the centre of the object is at DS 0,0,0 and that is set as the object origin regardless of the co-ordinates of the origin of the object before import (caught me out more than once). This means you may have to scale the object in the external modeller to centimetres before import into DS, so the origin stays where you model it.

    Regards,

    Richard.

    Also make sure there are no DAZ assets being used, including donor rigging or textures since DAZ doesn't allow use of it's assets in secondlife last time i checked. Not sure why you would be using DAZ at all since there shouldn't be any genesis figures in secondlife.

    There are two types of coordinate systems, right-handed and left-handed. You can determine which one you're dealing with the "Right Hand Rule" like this:

    With your hand, point your index finger along the +x axis, and your middle finger along the +y. Which ever hand you use where your thumb then points along the +z, is the orientation of your coordinate system.

    Wherever you got your OBJ from uses the one, and Daz Studio is using the other. You can fix it by a rotation followed by scaling in one direction by -100%. I can never remember which ones, it is easy to see though, but just realize that the second operation to fix it is not a rotation; you have to mirror it or a non-symmetrical object will be reversed.

    The DS OBJ import dialogue will do this for you (once you know which settings are needed).
