Add geometry resolution without Dynamesh or subdividing your entire model.
Here is a super useful tip for ZBrush users from Pablo Munoz G.
Ok, here it is: You hold ‘Ctrl’ and start masking an area of your model. Just before you let go to finish your mask, hold ‘Shift’ and release the click. When you finish, check your wireframe (Shift ‘F’).
Here is how this trick works:
NOTE: This won’t work if you already have subdivision level
You can achieve the same result by masking an area, inverting it and simply use the good old ‘Ctrl+D’ shortcut to subdivide. When you perform this action, with a portion of your model masked, ZBrush will only subdivide the unmasked area.
Also, you can do the same thing by hiding an area of your model and use the subdivide shortcut again. ZBrush will subdivide only the visible part:
So, you probably already knew about this feature, but the ‘Ctrl+Shift+release-click’ trick to add geometry is a hidden gem. It might not be the cleanest of processes, but it certainly is a fast way to add more polygons just when and where you need them.
