I've got a really dumb question. I've been concentrating so much on this course that my brain appears to have fried so many apologies in advance.
At 0:30 (ish), a line is erased from the overlay. The only way I can seem to do that is by using "erase alpha" but I don't believe that is what is happening in the video. How is the line erased in this case ? I am sure we did that earlier in the course, but I cannot find it in the videos.
Thanks and apologies again
@jlampel - Ah I see. I'm using my iPad as a tablet and it hasn't got that functionality. At least I now know I was on the right track with "erase alpha". When I have done the sculpting tutorial, I am going to decide whether I should buy a dedicated graphics tab or stick with my iPad.
