This video shows the new Celestial 2.5 Body coming in v7 of Celestials ( it may also be released as a Stand Alone Body for converters should I get a good reaction to it ). It demonstrates how it was designed to work with HDTPhysicsExtension as well as leo4deks Collision XML to give the body a natural and realistic feel while still maintaining a high fantasy style. Note that the Realistic Test is a different XML effect that does not include Collision, and that leo4deks Collision XML offers Collision but has a different Physics Effect. The two have not yet been combined.
NOTE: v7 of Celestials is still in Alpha and will not be ready for some time.
