 So, you don't know how to import and export objects in ZBrush. Not a problem. Let's say you made an awesome object in Blender and you want to bring it into ZBrush. Well if you go to the right and you'll see this tool menu, click the star, click import, find your object, you're done. Your object should appear and you can begin sculpting onto it immediately. Now be careful when doing this because if you import another object while an old object is selected, it will be replaced. This is why I always click the star first before importing new objects. Now inside your object you will see a subtool menu. Now I'm about to oversimplify this but basically the easiest way to understand this is a tool is basically a project and the subtool menu is the equivalent of the scene collection tab in Blender. It's the thing that holds all your objects. Inside one project you can have multiple objects. So once you're in the tool, under subtool, you can append new objects. If you want to add an object that you imported, just select it like this. You can click the eyeballs to make things visible and if you hold control, shift and left click, you can turn visibility off and on for every object simultaneously. However the currently selected object will always be visible, even if it has visibility turned off. You cannot edit an object unless it is selected. If at any point you have multiple objects and you want to quickly edit one of them you see on the screen, just hold alt and left click it. And every object in ZBrush has its own undo history. So if I work on the shoe and then go to a different object and start doing control z to undo, nothing is going to happen because I haven't worked on this object yet. If I want to undo what I did on the shoe, I have to go back to the shoe and then start undoing from there. Also you can left click and drag these objects up and down the hierarchy or if you want to make groups of objects into a folder, you can do it like this and at any point you can rename them here. Now let's say that you want to import multiple objects at the same time. You bought a hundred swords and now you want to go through them in ZBrush. To do that, go to ZPlugin, Subtool Master, Multi-Append, select all your objects, enter and it might ask you a few questions, just say compatible with Z to everything and all your objects will be available. Hope that helps. And as always I hope you have a fantastic day and I'll see you around.
