With Character Creator 3 Pipeline you can buy additional pre-made add-on packs, or you can import clothing, hair and accessories in OBJ format and apply them to your character in CC3. This new import option allows you to bring in unlimited clothing, hair or accessories from sites like Daz 3D, Hivewire, Smith Micro, Turbosquid etc.
Character Creator 3 doesn't export in .STL format. You can export to OBJ or FBX formats only.
Unfortunately we don't offer individual student discounts at this time. The special pre-order prices will only be available for a little while longer so if you do plan on purchasing I would do so as soon as you can. The pre-order special price for CC3 Pipeline is currently $129. The full price is $199 but there may be other special offers at the time of release. This has not yet been confirmed.
