i'm trying to make a cube and spear it with a cylinder. cube is positive, cylinder is negative. then i want it to appear as a round hole right thru the cube, so i can see thru it. no matter what i do, it won't work. cannot find the group objects option anywhere, in bryce5. i 've linked the cylinder to parent cube and even made the cylinder transparent. nothing works. been trying every combination possible for about a week now.
