Rounding Corners
To create those corners that the deformation can not do is simple. Many areas of the caves dont simply have a straight edged corner, nearly all of them and rounded. As my scene is created with meshes i click on the borders and extrude to the point i want them to. It's just a matter of applying this multiple times to get the rounded corner.
NOTE: The more times the mesh is extruded - the more polygons will be created. Sometimes it is best to create just a few so the corner is visible and then use the 'SMOOTH' modifier to get the effect needed.
