When i made the pocket for the dress it was very blocky due to the lack of sub divisional lines. But i did not want to add lots more lines in which i would have to play around with to try and get the pocket to become smoother.
Looking at the pocket, you can see the thickness of this, which i think is way to thick to be for material, so i needed to extrude the pocket so that i could make this become very thin. But i had thought about how i needed to rotate the pocket so that there was a gap at the top but not at the bottom. So i had to play about with the vertex and attach the edges to the dress.
With the pocket made but still blocky i needed to smooth it out. And with the helpful tutorial that i spoke about in earlier posts from youtube. He spoke about using something called soften edges. I thought this was just the standard smooth tool, but i was mistaken. With the soften edge tool, i can select the edges i want to become smooth in the tool bar normals and click soften edges. This is such a helpful tool if you do not want to smooth out the whole object and this helps the poly count to be lower. I found this out when experimenting with the two different tools and noticed that using soften edges lowered the count more than going into mesh and using the smooth tool.
