So I was working on my model of a Ukrainian Gerb, tried my best to make right topology but when I pressing ctrl + R the loop cut creates but it won't slide.
Can someone explain it to me, I am not understanding how and why it works like this?
Indeed, Vitalik KKucharskyi ,
Omar is right.
Look at the difference here; the left one can Loop Cut 6 Slide, the right one can only be Cut:
Same here, this Loop Cut can't slide:
All those newly created Vertices can slide along the Edges they Subdivided, except that top one.
