Hi! I'm quite new to 3dCoat and wanted to start something as an exercice: a space suit My idea was to first import a full body object, then "offset" or "inflate" the volume/surface slightly to have the base of the cloth surface and start sculpting from here. I naively try the Grow tool with a (E) rectangular selection but that did not work. Obviously I'm not using the right tool : ) What would be the recommended way to "offset" or "inflate" a all object at once, not using brush ? I'm pretty sure it must be pretty obvious but I can't find my way out in this one.
