I'm new to ZBrush. I am working on a model using zSpheres. I get halfway through it, and I decide to save it. (I do this in part because this program crashes frequently.) I know to save it as a Tool, not as a Document. OK, I save it as a Tool. But later, when I try to reload it, I can't edit it properly. I load the Tool; I create an instance of the Tool on the canvas; I hit T to edit it; I can edit once or twice; and then abruptly I no longer can edit it. Instead, every time I click, now I get a new instance of my model.
Please, please help me. I've tried to post on the Zbrush forums, but they don't seem to work right.
