also: - get the ribbon spine out of your head -- there are far better ways to do a spine in Soft. - you need not have UVs to save your weighting natively. :) - IK comes "free" with any bonechain, you don't need to create an IK handle. - there are no "disconnected nodes" floating in your scene, except possibly those in ICE or the rendertree. For example if you have something constrained to another, and delete the other, your constraint ops will disappear into the cosmos and not linger in your scene. - always use "2D" bone chains in Soft. the 3D one is for very rare cases. - Maya's "history" concept = Softimage's "operator stack" - Maya's "UV sets" = Softimage's "texture projections" and Maya's "UV projection" = Soft's "texture subprojections" - In Maya you have one history stack, in Softimage you do also BUT it's split to several sections, Modeling, Shape Modeling, Animation, Secondary Shape Animation and sometimes Simulation and Post-Simulation. This lets you do witchcraft like have a finished rig and modify your topology while having UVs, shapes, materials, clusters, weight (influence) maps, etc. cleanly adjust to it automagically. This feature will save your life. - "Freeze" button will make all your operators permanent, and ruin your rig. "Freeze M(odeling)" will only freeze below the Modeling marker. As I recall, it's quite tricky in Maya to do the equivalent of a freezing of the topology modifiers you may have applied after the rig was done. - Freeze Translation will reset your pivot to the parent's, or if no parent, the world center. In Maya's equivalent it keeps the pivot in place. To keep it in place, use Set Neutral Translation instead. - You can't add more bones to an existing bonechain, or remove bones, without having to recreate it completely. (Annoying, I know.) You can always chain some chains together of course. - Be aware that Neutral Pose is not the same as putting the object as a child of a parent in the same transformation. For example if you rotate a child and neutralposed, when you have animated it translating around and expect to adjust the position curves, for example posY, to actually go UP in the zeroed (neutralposed) orientation of your child, it won't, it will always be relative to the parent's transform regardless of what the neutral pose says. Also, FYI, neutralposes can be undone (Transform->Remove Neutral Pose). - ICE is awesome for custom deformers and many, many things.
