The topology brush in both silo and this plugin look great for demo vids, but I’ve found its a bit too loose and unpredictable. Drawing out a new mesh should be somewhat freeform, but not that free!
The other topology tools really caught my eye though. Drawing out strips seems perfect, as does extending the surface by dragging on any vertex or edge. Much closer to the way I think; define major planes then join them together. The optimiser tool is pretty impressive too.
My main concern with the 2.5 preview video is the resultant mesh doesn’t look like a regular optimised mesh. It looks, for want of a better word, ‘zbrushy’. I know its early days, and I expect the layout will rely heavily on the user, but its hard not to compare. The max video looks like it generates useable topology in a controlled way, the zbrush 2.5 videos look like too much magic is going on… I worry that we’ll end up taking meshes into 3rd party tools for final vertex tweaks, which is a shame.
Anyways, this is all counting unhatched poultry. We’ll find out in a few months won’t we?
