Hi,
If I have nicely sculpted ear or eye on other side of model, is there some way to mirror copy/paint it to another side? My model is not symmetric so I can’t use reSym…?
Any kind of tips are welcome! Thanks 
you can clone the model, append the model, mirror the model, then pull out some geo for the ear. use the project brush to pull from one mesh onto the other. It will be sloppy at first and will require some resculpting but you’ll have the major forms so it will pretty much just be clean up work after that.
