There are so many graphical issues with unions, that it gets annoying.
E.g. I was negating a part of a plane I was making, and on one side the brick looked normal whereas on the other side (the negate was symmetrical) it has many creases. This just made it look ugly but I had to go along with it as there was no way of fixing this.
Also, there are many other issues with Unions, e.g the triangle limit and sometimes the error where you 'cannot union'. |
