I'm trying to weight paint the beak and the jaw of my bird,but I realize that I'm not able to get the result I want. Infact,when I weight paint the jaw in red and I rotate it on the X axis,it works,but the beak doesn't. When I weight paint the beak with the red color nor beak nor the jaw are colored perfectly. I would like to know if I can weight paint only a part of the bird,not everything. For example,in edit mode,I have selected only the vertices of the beak and I have inverted the selection with CTRL + I and then I hid them because I want to weight paint only a specific section. Why I want to do this ? Because when I paint a specific region of the model in weight paint,the painting is not carefully and I paint also the borders of a region that I don't need. I don't know if I can do it in weight paint mode,so,I thought that I could do it in edit mode....check the attached video,thanks.
