Say you have a quad, can one cut a corner out of it using two user clip planes? What I want to achief is that people can look into my geometry by cutting away a small part. What I tried was setting up the clip planes to { 1,0,0,0 } and { 0,1,0,0 } but what remains is only one small part instead of such a small part being cut away. Thanks for any help.
