What is Silo?
Silo 2 is a focused 3D modeling application with the ability to effortlessly switch between organically sculpting high-polygon models and precisely controlling hard-edged surfaces. It can be used for anything from creating 3D characters for video games and movies to quickly exploring 3D architectural ideas.
Silo is currently being used at top studios worldwide as both a stand-alone design tool and as a versatile element of a multi-software 3D graphics workflow. It is available for both Windows and Mac OS.
About Silo Professional
Silo Professional is the main version of Silo, which gives users access to everything Silo has to offer. This includes Silo's core modeling toolset, as well as advanced features for UV editing, displacement painting, re-topologization, and more. Read on for a feature breakdown and comparison.
Advanced UV Editing
Silo Professional offers multiple types of unwrapping, including LSCM, Planar Region, XYZ, Per Face, and By Neighbors, which heals UVs based on the UVs based on the surrounding area. Different unwrapping methods can even be used on parts of the same mesh for optimal results. UVs are preserved during modeling operations, so modeling and UV editing can be freely interchanged with little to no cleanup. (This is particularly useful when a last-minute modeling change needs to be made to a "finished" model.) As described in the Silo Core section, clutter is significantly reduced by allowing regular geometry editing tools to be used to edit UVs wherever it makes sense. Even the displacement brushes, particularly the Smooth brush, are very useful when applied to smoothing out UVs.
Finally, brush-based displacement painting has been well-integrated into a traditional modeling environement. Silo's brushes integrate seamlessly with the rest of the modeling toolset. If the model is subdivided, the brushes will affect the subdivided shape directly, otherwise they will affect regular geometry. As with UVs, displacement is preserved where possible during modeling changes, so the brushes can be used alongside other tools as the model develops, rather than solely at the end of the process. Painting is smooth and natural, and works well with tablets. Displacement maps and normal maps can be generated and exported from any subdivision level, or even from two completely separate objects.
With the popularity of displacement painting in Silo and other applications, as well as the common usage of 3d scanners, modelers are frequently asked to create a new, well-formed model with a high-poly shape for reference. This process is frequently known as retopologization, and Silo's Topology Tool provides an innovative solution by allowing users to directly draw new topology onto an object using a pen-like tool. Silo also offers Surface Snapping, which effectively turns every tool into a topology tool by snapping edited geometry to an underlying shape, and the Surface Tool, which allows users to quickly in interactively draw out and tweak strips of polygons.
Complex Scenes can be easily managed in Silo Professional via the Scene Editor, which displays the scene in a tree-like structure and allows layer-like editing of objects and groups. Selection, display mode, locking, and visibility can all be quickly modified from the editor.
Silo Professional offers precise numerical control of the position, rotation, scale, size, distance, and angle of selected geometry via the Numerical Editor.
Three powerful snapping modes are available in Silo Professional. Grid snapping snaps to the customizable workgrid, Component snapping snaps to the vertices, edges, and faces of an object, and Surface snapping smoothly snaps to the surface of unselected objects. These snapping modes affect nearly all geometry editing commands.
Along with the .sia, .sib, and .obj 3D formats supported in Silo Core, Silo Professional also supports import and export of .3ds, .dxf, and .fac, as well as the export only of .stl, .pov, and .rib.
