McNistor or MartybNz, to avoid duplication, could you introduce curves' management and its manipulators in Softimage? For example, for the moment, it is impossible to “break” the curve in houdini.
katana13, this thread is created for modeling and viewport interaction only. Animation is a different subject and I wish to keep it out of this thread.
There si ghosting. With that you can isolate current object from the ones that are outside. Default shortcut is Space+Y (or just Y if you are in View Tool)
For something more like XSI isolate selection tool:
This is what you probably want:
Thanks for the links. In the youtube video the approach of using takes is similar to other apps' layers, groups and in case of XSI passes and while being powerful for scene management are very slow for purely modeling purposes where you want to simply isolate an object in viewport only to quickly edit it without the clutter from the other objects.
The scripts you gave link to might do the trick (can't test them right now).
