mwah, XSI has some nice modeling capabilities, but Softimage is definately focusing on character animation and not modeling. I’d not use it as a main modeler in it’s current state, the only modeling advantage it has over Modo is history. But other then that it has too many things that should be interactive in screen, controlled by them sliders. Sliders are neat, but not for everything.
And then there’s simply too much basic modeling stuff I use in Modo all the time missing from XSI’s modeling tools.
Take something like selection tools for instance, there are several selection tools in XSI but the only one actualy working is the default rectangle selection tool. All the other selection tools are ray cast, even in wireframe mode. So no matter how hard you try to select all the vertices there’s always a few that are blocked by others you’ll miss. And the rectangle selection tool is not the best one to use while modeling.
Then there’s this silly “add polygon” tool from the 80’s where you actualy have to click on every vertex, clockwise and in the right order to create a polygon. And when you create one selecting the vertices counter clockwise, all you can choose to do is flip the poly’s of rest of the object.
What I also find very annoying for modeling is the Gimbal Lock viewport navigation in XSI and the fact that the view can only be centered around selected components. As soon as you deselect the components you’re focussing on and want to rotate the view you loose focus and the navigation rotates around the object pivot again.
An example; suppose you’re modeling around the eye area and to focus your view you select a bunch of vertices and hit “F”. Now as long as you keep those vertices selected XSI with rotate the viewport around that COG. But now you want to use the Tweak Tool with proportional falloff, so you deselect the vertices. Now XSI will rotate around the object pivot, and you’ll lose focus as soon as you rotate the viewport. So you always have to keep something selected to keep your eye on where you’re modeling …very bad…
XSI is really great for character animation, it’s rigging, enveloping and animation tools are realy great. But for modeling…nah…
