Hi again @jlampel ! I have a problem: I want to try out RetopoFlow, but it hasn’t worked since I installed it. Here are some images ( I tried with other forms, too…sculpted and everything. I forgot to show that in the picture. Still couldn’t select):

Besides a warning about it being beta, sometimes Blender doesn’t even show the tool at the header. When it does and I press the “Make Target” (or whatever it was called), I’m in the new area, Contours is selected, but I can’t do anything. There’s no cursor or anything, just the symmetry line. Even that actually works.
When I press escape to leave RetopoFlow, suddenly I can’t select anything in the regular Blender window. That bums me out. 🙁 I just bought it a few days ago. 🙁
EDIT: Never mind…once I restarted the computer, it worked. I have to remember that I hold Ctrl+drag to make a new contour or whatever. Phoo! I’m still gonna look at those livestream vids!
