Hey there!
I have been struggling with retopology lately. When it gets tricky for me is when I have In Front turned on and I see the wire and back of the other side of the mesh.
It makes it very hard to see. I know many others have this issue, and some use addons like Draw Xray or other tools to get around this.
However I am wondering how people solve this and other issues in Blender. What is your method of choice?
Currently my best option is to NOT use In Front so I can work in a solid object that hides everything.
