New to Blender, have a quick question about masking. I am greenscreening some photos, however some areas do not cut out correctly (space between ladder notches), so I have resorted to masking and using nodes in Compositor. I was able to add a mask around the object via Movie Clip Editor, however when I add another mask to the space between the ladders (adding a square between), this second mask does not show and the greenscreen is still visible. I am using nodes similar to how CG Geek on Youtube has in his tutorial. A second mask option does not appear when I include another Mask input. Any help is appreciated!
