Curved lines in between vertices here´s the thing: I´m trying to give a more round like look to my model by modifying the lines in between the vertices, but I don´t know how. Below there´s a picture of what I want (took a snapshot of a video on youtube) I asked the artist how he does that but he doesn´t answer. I tried applying a curve modifier but it gives me a message of error that says "modifier disabled skipping apply". Is that how it´s done? by using the curve modifier? and if it is...how do I enable it?
Thanks in advance, I´d be really grateful for any help you might provide :)
