Get the hang of re-DynaMeshing
Let’s turn Polyframe on so we can see the underlying structure by pressing Shift+F. Go ahead and select the Move brush: you can use the shortcuts from the bottom of the screen or the brush’s thumbnail to access the library. Click the sphere and drag to create an interesting shape. The polygons are now getting stretched, but we can hold down Ctrl and click and drag on an empty space to re-DynaMesh.
This is how the stretched polygons looked and the result after re-DynaMeshing.
You can see the available brushes by clicking this thumbnail (the icon will change with each brush).
