Silo 1.3 will bring in a great looking new tool: the Topology Brush. It actually allows you to PAINT the desired mesh topology over existing polygons…check it out here:
[b][i]"One of the most direct uses is to free up your modelling. You can work out the form in Silo or any other application (say, ZBrush or even 3d scan data,) without worrying at all about edge flow or topology. Once you’ve gotten the basic form you like, you go in and draw a new topology onto the mesh. A new mesh is created (with vertices at the intersections of the lines you’ve drawn) based on your lines. This is many times faster than trying to rework the topology using split tool, spin edge, etc. Another example is making a low-res version of a high-res model. You can import the high res, and then draw out all the topology for the low-res with regular sorts of pen tools - adding lines, deleting lines or parts of lines, continuing from existing lines.
For many people, there can be a disconnect between the shape they see on the screen (say, a box figure), and the shape they want to end up with. Often they can see how they want the edges to flow, but don’t know how to get from point a to point b. And the time it takes to get between the two can kill the creative flow. So you could plan out the shape with a simple box figure, draw a more complex topology onto it, and then move the newly-created verts into a better position."
Nevercenter’s Silo looks set to have one of the brightest futures in the industry. BTW a final Mac version is out too!
