I tried to search an answer to my question, but didn't find a solution so far, so looking for Your help. I'm trying to create a modular sci-fi corridor. As You see in the first screen shot - this is the topology resulted, when I cut window in the simple shape, and after apply bevel to window edges - there is some pinching arises as seen in other two screen shots. What can I do to eliminate those pinching? I want to keep it low poly - I need to transfer this item to Unity.
