Skiriki asked for this. I've been putting it off because it's very involved, but it is a good workflow to know if you're doing Poser/DAZ props and outfits on a budget. Blender is free and, while it has notable shortcomings in terms of painting across contiguous nonidentical UVs (which is why it doesn't compete with Zbrush and 3dCoat in those areas), it is great for base meshing and many kinds of sculpting.
Some preliminary controls in Blender:
Scroll Mouse Wheel: Zoom in and out.
Hold Mouse Wheel/Drag: Rotate view dynamically.
Shift/Hold Mouse Wheel/Drag: Move view horizontally/vertically.
Numpad keys: different orthographic views; 5 switches orthographic/perspective.
Tab: Switch modes. You can see the Mode dropdown just below the 3d window. It will say Object mode when you start up Blender.
Right Click: Select an object.
G: grab an object to move it.
Right-click after G: Let go of moved object, letting it snap back to its original
