About the Software

Available for an incredible low price exclusively on Steam, 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.

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.

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.

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.

Features

  • Zen Workflow - Silo's careful design and its focus on pure modeling allows it to have a free, uncluttered feeling which is simply not possible in larger applications. Whether you are working to precise specifications or sketching out your thoughts, it is much easier to do so in a calm, focused modeling environment. This benefits professionals who are coming to Silo to escape slower, more complex software. It also benefits hobbyists and students, who are able to learn everything they need without having to deal with anything they don't need.

  • File Formats - Silo supports import and export of .sia, .sib, .obj, .3ds, .dxf, and .fac, as well as the export only of .stl, .pov, and .rib.

  • Advanced Polygonal Modeling - Silo offers a comprehensive set of interactive, context-sensitive tools for rapid polygonal modeling. The workflow is focused on having a few powerful, intelligent tools, rather than a separate command or option for every conceivable function. Additionally, "sticky key" functionality allows tools to behave differently if a hotkey is held down. Key modeling tools include Break, Tweak, Cut, Bevel, Slide, Scale, Extrude, Polygon Tool, Edge Tool, unlimited Undo and Redo, and more. Modeling can be performed with or without manipulators, including the Universal Manipulator which combines rotate, scale, and translate into a single manipulator.

  • Comprehensive Selection Tools - Robust selection tools are the key to great modeling, and a quick look at the Selection menu shows Silo's development has focused heavily on this area. Some highlights? Multi Select mode allows users to select vertices, edges and faces without changing selection modes. Tweak selection allows a user to grab, move, and deselect a component with a single click. That and many other tools work with Soft Selection, which smoothly distributes changes throughout a shape. Paint, Area, and Lasso selection types are supported. Select Visible and Select Thru functions are both available - by default, use the left mouse button for Select Visible commands, and the middle mouse button for Select Thru. A separate Undo is available for cycling through recent selections.

  • Subdivision Surfaces - Subdivision surfaces offer a smooth, high polygon shape, and are easily accessible in Silo. Using default shortcuts, simply press c to subdivide as many levels as you want, and v to unsubdivide. Modeling can be performed in real time at any subdivision level with updates shown directly on the subdivided shape. Edges can be creased to keep them sharp at all subdivision levels.

  • Unparalleled Customization - Designed to fit into any pipeline, Silo is the most customizable modeler available. That includes complete customization of the mouse, keyboard, and graphical interface, allowing it to closely emulate other applications a user may be familiar with, or perform tasks (such as assigning up to 40 different commands to a typical mouse with keyboard modifiers) which no other application can. Favorite tricks include assigning undo/redo, grow/shrink selection, and to the scrollwheel, or simply putting frequently used commands on the right mouse button with modifiers. Silo's button pages allow users to create their own multi-page interfaces, and assign any command to any image. The interface and color scheme are also highly customizable. Customizations can be easily imported, exported, and shared. Even the Primitives menu can be customized with frequently used models or settings.

  • Advanced UV Editing - Silo 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.) Clutter is significantly reduced by allowing regular geometry editing tools (such as Break, Merge, Tweak, Slide, and Soft Selection) 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.

  • Displacement Painting - 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.

  • Retopology - 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.

  • Scene Editor - Complex Scenes can be easily managed in Silo 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.

  • Numerical Editor - Silo offers precise numerical control of the position, rotation, scale, size, distance, and angle of selected geometry via the Numerical Editor.

  • Snapping - Three powerful snapping modes are available in Silo. 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.

As you can see I've played this game a lot. Unfortunately I'm not sure how one would win this game with over 300 hours played it remains a mystery.

Joking aside Silo 2 is a very competent low poly modeler with fairly easy to use UV unwrap tools.

On the downside its clearly no longer updated or in development (although the company that owns it always denies this despite years of no bug fixes or version changes) so if you do happen upon a bug you will have to learn to work around it.

Generally its cheap entry price and simple approach to low poly modelling is refreshing enough its worth picking up when on sale for sure ; otherwise you might want to check out other options like Blender 3D while complex, with overtly complex UI it is constantly being improved upon and free.

Silo is a modeling package that is designed to do modeling and nothing else. By focusing on just modeling however, it's able to make itself into an intuitive tool used for quick modeling and UV mapping.

The interface has some very smart, intuitive features (hitting a hotkey combo while hovering over a menu option will assign that hotkey to the menu option for example) that make using the program quick and easy.

With it being a smaller program with less community than, say Maya, 3ds Max, or even Blender, finding help on line for modeling beginners or Silo newcomers can be troublesome. Other issues include the fact that it can be fairly easy to crash the program if you're not careful.

However the ease of use the program brings to the table, not to mention it's incredibly fair price make it a program to look into if you're in the market for a affordable helpful modeling program.

I use this for modelling, and it's great. Place in a cube, cylinder, sphere, head, or full body, and just edit it into whatever. People say it's bad, it's not supported, it crashes all the time... But that doesn't matter to me, as Silo 2 has always worked for me. It's crashed once or twice, sure, but I always save after every major edit as a force of habit and after I'm done I can export it and put it into Garry's Mod. I found this incredibly easy to master, creating a modified base head with a massive nose and holes all over his head within the first 10 minutes of using the program, and now I can create much better models ranging from simple helmets to awesome armoured soldiers. Simply put, I think this software is fantastic and the lack of support doesn't matter at all. If you disagree, well, that's your opinion.

Easy interface, low level of crashes (for me), very fun to use. But the price is a bit high! It shouldn't be about $70 bucks honestly, it should be what I paid for on a sale, $40. The app itself isn't worth $70. I would suggest getting a free app that can do a lot more than Silo, yet harder to get used to, but if you really want silo, wait for it to go on sale.

DO NOT BUY THIS!
If you test the trial version and most things work DON'T GET FOOLED!
As soon as things become more complex than a CUBE the software will crash on cutting polygons, boolean operations, YOU NAME IT!
And the worst part is that you can NOT fix your mesh, because it's the software that completely destroys it!
It's next to impossible to track down what action destroys your mesh in order to avoid using it since it's freaking random!
Save your money and your time!
