1. Go to the [female upload/male upload] page according to your Shepard's gender.
2. Follow the instructions on the upload page.
3. If the YAML file uploads successfully, there should be a button and you can just generate the code right away.
4. You can generate the code again on the [female code gen/male code gen] page (I will delete YAML files after they have been on the site for 24 hours).
If the upload does not seem to work, you can go to the [female code gen/male code gen] page and paste the YAML contents in the big text box to generate a facecode.
If the upload/generate buttons are not doing anything, try a different web browser.
I used this guide http://masseffect.livejournal.com/656484.html and made a script that attempts to automate most of that process in making the face code. THANKS BLUEFALL FOR THE GUIDE!
Also, thanks to Epic Legion for his Mass Effect 2 Save Editor site for providing the YAML Export.
I highly recommend you compare this against your Mass Effect 1 import into Mass Effect 2 BEFORE you put it into Mass Effect 3.
Did some changes to the code for possible fixes from jprospero.
cheekDepth_front: count right from center (not left)
cheekDepth_back: count left from center (not right)
Divide by 0.04 for both femShep and broShep (max of 0.6) (not just broShep)
I'm trying to make the site look abit better and I've merged the yaml upload and copy & paste into the same page.
I have changed around the male face code and now it should be correct, regarding the Hair settings.
