Happy modeling
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 Windows, Mac OS, and Linux.

A Step-By-Step Guide to 3D Modeling in Silo
The best way to learn is by doing. Antony Ward and Nevercenter's own David Randall team up to take you step-by-step from an empty screen to a high-quality character model, offering an extensive introduction to Silo's interface, tools, and workflow along the way. Available now from Amazon.com.

Tutorials, videos, and other resources on both Silo and the modeling process are also available throughout the site, including:

Pure, Focused 3D Modeling
Silo brings 3D modeling zen to artists via a clean, focused environment and a streamlined toolset, honed over years of development. It was initially born of our own frustration with the needless complexity and slow, unmanageable workflows of all-in-one graphics software. We single-mindedly devoted Silo to modeling, discovering that the modeling workflow could be made much simpler without sacrificing any power. This unique approach has attracted in equal number students, hobbyists, and professional artists in film, games, architecture, and other fields looking to maximize their production. (Read interviews with professional artists using Silo.)

At Silo's heart is an innovative, robust, and 100% customizable polygon editing toolset, suitable to both organic and hard-surface modeling. This polygonal base mesh is used to drive subdivision surfaces if desired: just hit C and V to navigate between subdivision levels and the base mesh at any time. Those coming to Silo from other applications will find that, despite having fewer tools, Silo isn't lacking any functionality. Instead, basic modeling tools such as Tweak, Cut, Bevel, Extrude, and Slide intelligently adapt to the task at hand based on context, drastically cutting down on the time spent switching or hunting for tools. (Watch context-sensitivity in action with the Cut Tool.)

On top of this core toolset we've added non-destructive brush-based displacement painting (especially useful for high res meshes or directly editing subdivision layers), advanced uv unwrapping, and the unique Topology Brush which lets you literally draw a new edge flow onto a 3D surface. Intuitive, advanced selection tools including Tweak, Loop, Ring, Path, Grow/Shrink, and Soft Selection are key to a fast, fluid workflow. (Watch how Tweak lets you instantly grab and adjust points, edges, and faces to organically reshape the model.)

Finally, we've priced Silo to be accessible to everyone. We strongly believe that inexpensive 3d modeling need not sacrifice any quality, and we've designed Silo to prove it.

Silo 2.3 Known Issues
All Platforms:
  • FACT exchange between Electric Image Animation Software (EIAS) doesn't appear to work. We are looking into it, and are in contact with the EIAS folks.
  • OBJ export then loaded into Substance Painter causes Substance Painter to crash. There are reports that importing the Silo-made OBJs into another package first (like Roadkill) and then exporting again will produce OBJs that Substance Painter can read properly.
  • Empty meshes (deleting all polygons out of them) cannot be finally removed from the scene, even in the scene editor. A workaround is to select the empty object in the scene editor, create a polygon with the Polygon Tool, select it in object mode, and then delete it.
  • Meshes with non-standard topology, such as having three or more faces share the same edge, will cause subdivision to produce corrupted results. Boolean operations and other operations may also fail on such meshes. It is planned in the future to have a mesh cleaner operation that can help remove problematic pieces of geometry for situations like this.
Linux Only:
  • Some desktop environments, such as Gnome, bind the Alt key to move windows by default. You must go into the window or keyboard preferences of your desktop environment to use a different key (such as "super") instead, so that Silo's default use of Alt for camera movement will work.
Windows Only:
  • Old data from Silo 2.2 and before may reside in the "Silo Data" folder inside "My Documents". This old data may cause issues as the newer Silo will try to use it as-is. If you run into missing icons, key bindings, or other issues, please rename Silo Data to something else. Silo will recreate the folder with the new default Silo 2.3 data, and you will be able to set up your preferences after that from within Silo.
