Okay, everything set up. Now we held into the base forms. So now we have this simplified geometric, we go into the geometry tab on the right side and we add one level of divide to the geometry to have a better control on that. So you can see it has now more resolution. And now we can work with that much better. On the right side, now we can delete the lower level of the subdivision.

And there we go. We that we added up the subdivision permanently to our sphere. And now that is our basic shape. If you press the shift z, you can toggle on and off your reference image. Now if you want to make the exact basic shape, as we have on our reference image, we need to move your move our reference image above our 3d model. And now we can form our 3d model to the reference image to see our 3d model behind the reference image on the spotlight screen, you can bring down the opacity level.

Alright, so now you want to use the Move brush in the brush bullets, you will find that and with that, you can form your base geometry to the reference image. You want to turn on the symmetry with the X key or in the transform menu on the upper side. There is another useful feature what I'm using during my process that named dynamic subdivision. With that, you can give subdivision level to your geometric But this didn't added to the geometry permanently. It is just a preview. That is good because you don't need to subdivision levels to your surface.

And you can go back and go go for a higher subdivision. We just one keystroke, that keystroke is d you will have this Papa probably with us you too. Would you like to out to activate dynamic subdiv? Or you want to give subdivisions. We want that dynamic subdiv now, so we click on yes or on always Yes, if you don't want this pop up anymore. If you want to go back to the lower subject, you need to hit down shift plus d. But why is it useful for us in this case, it will make the base form of the head.

You can do that with that lower subdivision. But if you want to check out how it looks like if it would have a bigger subdivision level, you can check that with one keystroke without adding any permanent subdivision levels. So you can see I will check the geometry the smooth one and I will work on the smaller one. Okay, now we made a lot of things. So I suggest you to save your project ZBrush has a quick save feature, what you can reach in the Preferences menu on the upper side and it is set to default and it is made a quick save every 20 minutes. But we want to make our saving manually sometimes.

So for that You need to hold down the Ctrl S and you can save your project anywhere you want. In the last section I will show you how you can save the position of your geometry behind the reference image.
