I think it would be great to be able to use .ccSlider files (for example, from this pack - https://forum.reallusion.com/Topic386118.aspx or ones that created manually by the user) in the Morph Creator.
Right now it is accepting only obj or iAvatar files. The current workaround for me is to create an iAvatar file for each morph, but it is a very time-consuming process since it needs to be done for every character individually.
