I found a video topology tutorial last week showing someone sculpting a rough head then polypainting where the new topo lines should be, then using the topo tools etc.
I can’t find it!! Thought it was posted here, but no joy… does anyone know what I’m on about/where to find it please!
I remember it from a long time ago as well, but can’t find it anymore.
It wasn’t really a tutorial. It just showed how the artist uses polypaint on the original model to draw the new topology that he wants. Then he uses the retopology tool and just follows those lines. Just follow the links to learn about those two features. You should then be able to do what you want.
Also, this thread has some excellent tutorials that may help you out overall:
Thanks aurick, I will look into the links you have posted.
If anybody does know where this tutorial/link is, please help me/us out! 
you could look into this one: http://gnomonology.com/tutorial/98 (by Meats Meier)…think he does what you’re looking for.
that meats tut goes over the tools pretty well but his topology is a mess.
Maybe take a look in my tutorials if it fits your needs.
Simply follow the links below.
There is a second videotutorial on Gnomonology from Ryan Kingslien about retopo with polypainting.
Thank you a lot Rastaman for your effort you put into your free retopo tutorials. They are very inspiring!

Here is what I used to learn the topology tools, awsome thread I might add. Took a lot of trial and error but still great.
Yeah I think so… thanks a lot!
