In this short tutorial I will show you how to sculpt a sphere and turn it into something interesting.
First let start a new Blender project then delete the default cube and add in a sphere, Mesh->UV Sphere.
Next add in a Multiresolution Modifier
Next click once on the Subdivide button under the Multiresolution Modifier to increase the Preview, Sculpt and Render value to 1.
Then switch from the Object Mode to Sculpt Mode and make sure that Mirror x has been selected. This is just like using the Mirror Modifier on our object.
Select subtract so we can dig a hole on the object, before that make sure you switch to Front Ortho View first. Now start to sculpt a hole on the right part of the sphere.
Now you should understand why we need to set the X Mirror at the beginning of the tutorial.
Next click on the Subdivide button once, not too many time, just once to smooth the object a little bit.
Next switch from subtract to add.
Create below figure.
Click on Subdivide again to smooth the object.
You can also press the F key then move your mouse to increase or decrease the area of the brush as well as press the Shift+F key to increase or decrease the strength of the brush.
That is it! Hope you like this short sculpt tutorial, sculpt is not easy to master, you need to keep on practicing in order to perfect your skill.
