I'm trying to decipher what another member did to solve my problem of the shape of my mesh being altered when I subdivide it. Here is a link to Steamy_Steve original post, and I have also copy and pasted his solution below.
"If you store the vertices' position in a "morph target" before creating a new subdivision level, and then re-apply it on the same source-level, the new level's vertices' position is recalculated on that scaffolding, hence restoring the previous volumes and shapes."
I'm very new to Blender, so I don't know how to carry out the instructions above. Can you guys point me in the right direction? Like, how do you store the vertices' position in a morph target and how do you re-apply the positions. For example, what menus would I use and in which modes? Thanks!
