I wonder how I can make the edge between the white and the brown parts become rounded as the edges in the white? I made the below mock-up to help explain what I would like to learn. The edge on the brown part is made wonky and is suposed to stay that way.
Ctrl+R or Shift+V wont work. Of course I can adjust each vertices one by one in several diferent ways but I feel it sould be a way to reshape that edge, between the white and the brown parts, that is easier and more accurate than that.
Edge Flow (Set Flow) is nice for this, look here
Thank you. That seems like a good add-on.
Unfortunatly I just get a whole lot if errors when using it.
did you try to remove the last edge loop
then add a new one with Ctrl-R
It should follow the other curved lines !
happy bl
As I mentioned, Ctrl+R do not work since that places the vertices at an equal distance from the edges on both sides of it. The edge on the brown is too wonky for the new Ctrl+R loop to become a nice rounded shape.
Use edge slide or loop cut and enable the Even option. Perhaps would need to flip it depending on which side it chooses initially.
Thanx Stan. That is what I found out right now too. Thats the trick to do it.
Thank you all for helping me.
