Though can get a bit more complex in that under the model (namespace) there can be other organizational structures (nulls for example) that also do not move but are more to separate the different parts of the rig. One null for controls, one for meshes, one for deformers (null objects used in envelopes). Exampe: char_bob_midres_rig (model, at zero) - char_bob_midres_deformers (null, at zero) - eye_L_def (constrained to object in control hierarchy) - char_bob_midres_controls (null) - ice_host (null, at zero, calculates some deformation / kinematic data) - srt_M_ctrl (animatable) - offset_M_ctrl (animatable) - char_bob_midres_geometry (null) - body_M_midres_geo (mesh, at zero) - eye_L_midres_geo (mesh, at zero) Hope that clears it up. Also worth noting is that the model, and organizational nulls are all hidden, maybe even locked too to prevent them being disturbed (looking at you animators). :P Eric Thivierge =============== Character TD / RnD Hybride Technologies On June-20-13 1:06:15 PM, Ponthieux, Joseph G. (LARC-E1A)[LITES] wrote: Eric, Thanks. I guess now I am confused. I always interpreted Model as a toplevel parent. If I understand this right the practice is to have a transform group underneath the Model and the rest of the hierarchy underneath the transform group? All animation is then performed at the transform group and below while the model is nothing more than a "mini scene" container and kinematics at model level are ignored.

When dealing with objects with simulations on them that are under the model, the model's matrix if not at world zero can do funky things and have you pulling out hair and punching babies.

What's the point of expanding ICE beyond particles or point clouds if it's not recommended to use it on model assets? -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) Mymic Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party. *From:*[email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] *On Behalf Of *Peter Agg *Sent:* Thursday, June 20, 2013 11:40 AM *To:* [email protected]<mailto:[email protected]> *Subject:* Re: Models and ICE I would not recommend using ICE on models, to be honest - have a null underneath it and apply it to that instead.
