Anyone can help me a bit with a LoopTool issue? I am trying to turn some square circles I did on a model into rounded one but each time I press the circle option in LoopTools instead of making it look like in the third picture I attached (the expectation one) it just deforms my model as in picture two I am not sure what I am doing wrong and how can I fix it? How can I solve the problem of achieving the rounded circles without having all the areas affected? (I am new to blender so I am lacking some basic knowledge regarding how the program functions .. please explain the solution as you would do to a newbie) Thank you very much for your support!
Based on the opinion of the user above I managed to solve the problem. It seems like if I apply the mirror setting before playing with the LoopTools and after that selecting all the vertexes will lead to a smooth round shape instead of the square. So, in the end, it seems like indeed the problem is the fact that once LoopTool is applied it deactivates the mirror function leading to that shape.
So once you apply the mirror setting you will no longer have 5 vertexes in the middle but 20. Select all ofthem and then apply the circle option from LoopTool. That should solve the problem.
