How's this?
I really didn't add that many vertices tbh. I doubt it will cause lag.
I did have to make the chest wider to fit the shoulders so it does work well...
Btw rigging process has officially begun.
I agree.
It would be a waste of vertices, since... She really doesn't have much of a chest to speak of...
Make two versions, one for people who WANT lag, but "ZOMG BOOBIES!11!!!!" Aka 12 year old idiots.
And one for people who would rather have a more accurate model, with less chances of lagging out the game. Since MMD models are already VERY heavy on vertices.
I optimized the heck out of it though and even manually edited parts that used too many or too little vertices for joints. I know what I'm doing
I can post a pic with the triangulation showing if you want.
