What is the purpose of the RTE Encoder... RTEncoder is an encryption/decryption utility, and serves the same purpose as Maz's Objaction Mover. It allows you to encode a mesh in such a way that it can't be extracted and used without a special "key" to unlock the cypher. For instance, Lemurtek's Second Nature figures are built from the existing P4 figure meshes. To legally distribute these modified meshes, Lemurtek encoded them using the Posette or P4 Male mesh as the key. There's no way to use the Second Nature figures unless you already have Posette or the P4 Male (who are included in P4 and P5). I did something similar with my Millennium Catwoman figure, which was derived from Victoria and the Millennium Cat.
