I'm having a wierd issue with the plugin. I watched the videos and setup my HP mesh for retopo. I create my initial poly with the make polygon tool. I press control + shift and drag out my first extrusion and all is good and functional. However, after the first extrusion, if I try to do it again from any edge, it just automatically snaps to the surface of my HP mesh at a wierd angle.
Not sure what is going on here.
After messing around a bit, when I disable project edge extrude, I can extrude as many quads as I want and it appears to function okay, but quad auto weld does not work while it is disabled.
