      Mr. Sensei:

      I’m sort of getting the hang of this tool, but, unless I start my mesh by defining a high density poly strip first (and then add strokes to extend an edge of this), there seems to be no way to control the subdivisions that B-Surfaces has control of (in the original plug-in). How can I control how many subdivisions my strokes are divided into?

      Also, unless I want to do the entire retopo at one time, I lose the ability (once leaving Edit Mode), to go back and add to my first round of retopo meshing. What if I just want to pick up where I left off (before leaving Edit Mode the first time), and add to it, without adding a whole new “Draw Topo” operation?

      Thanks for these wonderful Blender streamlining creations of yours,

      Greg Smith

      Thanks for the props Greg. Glad you’re getting good use out of them. Regarding bmesh control, that’s not how the tool’s intended to be used. That’s the whole point of the underlying subsurface modifier and the “Detail” slider. The idea is to use as few (your actual mesh) polygons as possible to control the mesh medium which is using pure subdivision math to conform to each area. That’s why the tool only generates an exact face to grease stroke ratio.

      You can of course edit the mesh by extruding, adjusting adding edge loops etc… Does that make sense? Think about a king trying to dictate orders to every soldier personally, the point of this tool is to let you command your orders to the generals and let them handle the grunt work of controlling each soldier. I plan a tutorial on this feature some time in the future and it’s also possible it might experience some upgrades/changes between now and then.

      “I lose the ability (once leaving Edit Mode), to go back and add to my first round of retopo meshing”…
      This isn’t happening to my machine. Do you mean after you hit “Finish Draw Topo”

      Does this happen when you’re not using a high density polystrip and just using the tool regularly? Because you should be able to go back to it and edit whenever you feel like it so long as you don’t hit the “Finish Draw Topo” button before leaving edit mode.
