If the texture entry in the CR2/PP2 file specifies a path, it uses that, provided it is one under the poserruntime directory. If it isn't or is only a filename, is assumes poserruntimetextures as a default since this is where Poser also looks by default. Specifying a folder for textures inbound might be a good idea and something to consider for future versions. Since these are early, almost anything is possible at this point. Well, almost anything ;)
