i have some trouble with using subsurface modifier on this specific model. Some Edges are beautiful how i want it, but there is some tricky thing about this specific model which makes it impossible to add loop cuts from a certain 'direction'. It seems that i didn't fully understand how to make the right topology. Is there a way to do it better?
Picture 1 shows the edge which is to soft, pictures 2 shows the problematic topology. Picture 3 and 4 shows the good part which works fine because i can shift loop cuts from the bottom to the edge like how it should be obviously. Picture 5 and 6 shows that it is not a good solution to add loop cuts between because it create a noticeable 'dig'. I want a sharp edge (yellow) while maintaining an even curvature (blue)
