--
-- This script saves the selected layer and its child layers into an ASE file.
-- IMPORTANT: This exporter exports ONLY the Unreal relevant parts of the ASE format!
-- So you probably can't use it to transfer objects to application other than UnrealEd.
-- Although DeepExploration shows the objects properly.
--
-- USAGE:
-- The objects will be exported to the "objectdir" directory, located in the "content directory".
-- The "objectdir" variable can be changed bellow, the content dir can be set in the preferences window.
-- The name of the exported file will be the name of the selected layer.
-- It exports the first selected layer and any kids it has. (Child layers don't have to be selected.)
-- The children layers should contain the collision primitives, with the proper name. (MCDSP/MCDCX for UT2k4 and UCX/USP for U3)
-- The exporter exports the following vertex maps:
-- UV called "UV1"
-- UV called "UV2"
-- UV called "UV3"
-- RGB map called "Color"
-- If no vertexmap found with these names, then it assigns 0,0,0 automatically.
-- Set all your materials to a 89 degrees smoothing and use the separated polygon technique to achieve
-- proper shading. Unreal disregards smoothinggroup ID >32, so this exporter reuses the 0-32 range. Sometimes
-- this results in smoothing together otherwise independent, neighbouring poly islands. To fix this just cut and
-- paste one of them to change the order of the polygons.
-- Sometimes smoothing groups are not exported properly. A re-export after restarting modo will fix it.
--
-- You can set what unit in modo you want to be 1 unit in unreal. Check out the "UnitSystem" variable bellow.
-- I recommend using gameunits, but you can use a few other units, the object will be scaled properly.
--
-- Known issues:
-- You have to edit the parameters in the script. It would need too many arguments to define all aspects
-- of the export, I think. But if you want this changed, just drop me a mail.
--
-- If you find a bug or have a feature requests don't hesitate to contact me. :)
