To anyone who can answer this;
Doing some blendshape animation and I had a question. I am using join shapes because I created targets in brush. When you create a shape key, does blender store information for every vertex in target or just the vertices that are changed?
Presumably every vertex, otherwise it couldn’t maintain the vertex order. Also, it’s noticable how rapidly the size of a model bloats when adding shape keys, even if it’s only a few vertices changed.
