10 Improvements in Blender's Sculpt mode

This new tool basically sharpens edges between adjacent planes. Blender already has a Scraper knife, but Multiplane works like a V-shape angled chisel in traditional sculpture, with the digital advantage of adapting to any angle. It's quite versatile and could be an alternative option to other tools, such as Crease, if you'd rather avoid pinching the surrounding geometry too much when defining folds, corners or borders. In the Brush Settings panel you can set the angle, and enable a real-time graphic representation of the active angle while you sculpt (Show Cursor Preview). Quite futuristic.

With its standard deformation setting (Tri-Scale Grab), this tool is pretty similar to the Grab tool, but the displacement of the mesh is achieved with a softer transition, and it can be useful to reposition sectors of the 3D model, keeping the shapes and volumes of connecting areas better due to its elastic behavior. If you change the deformation type you can also generate Twist, or Scale a particular area with the brush.

This allows you to bend parts of the 3D mesh as if it had bones. This way, you can pose a character, or reposition protruding areas of any 3D model without even rigging it. The area being rotated will be calculated automatically, and you just need to move the cursor over the 3D mesh to see a representation of the area that will be affected by the rotation, which can be adjusted by changing the cursor Radius size, or the zoom in the Viewport (if Radius Unit is set to View). The Pose Origin Offset parameter can also be used to tweak the area being posed. According to the geometry, it might be helpful to use the new Pose IK Segments option, which represents the number of bones the temporal rig would have for the software to calculate rotations.

This tool applies Smooth, Scale, Inflate, Sphere, Random and Relax filters to the mesh. You can apply them to the whole model or parts of the mesh, by just clicking and dragging on the viewport. In this example I applied a Random and then a Smooth filter to achieve a cotton or wool effect in just one area of the mesh, by pre-selecting it with a mask.

This tool works with Dyntopo enabled, and allows you to reduce or increase mesh density in localized areas; for instance, if we generated unnecessary geometry around and area while sculpting it, we can use Simplify to clean around and keep the structure efficient. This can save time when dealing with complicated areas where a dense section of the mesh has deformed in an unexpected manner, or when it presents artifacts due to inter-penetration, which can sometimes be hard to fix with other tools. It can also eliminate other problems like mesh islands, parts of the geometry that have involuntarily ended up isolated.

Blender has many new options to work with masks within sculpt mode. Now you can extract parts of the mesh or slice them by preselecting them with masks, which in many cases can be faster than leaving sculpt mode to use Booleans or other methods.
