The image above shows the basic biped rig that was created for the model it was a fairly straight forward biped rig which was simplified to make sure the defamation of the skin was not effected to badly with excessive movement. I actually watched a massive series of tutorials from lynda.com which guided me through every stage of rigging and skinning and refining your rig to the point it was very consistent and reliable on the model.
I learnt fairly early that it is best to design your rig around what your character will be doing in the animation. So for this small animation I just wanted to do a slow, sluggish walk towards camera, no massive extravagant movements or actions, So I decided to use a biped.
The biped was fairly standard, once the parameters in the motion panel had been changed to incorporate the necessary amount of fingers legs arms ect, in this case 5 fingers same as a human. Once that was all sorted it was time to use the physique modifier to make sure the mesh fits the biped and gets the skinning process correct.
Once the skinning process had began using physique I basically whipped round the model and checked for anything irregular in the mesh and deformation when the model was moved in various directions. if there was I then modified the envelopes until I was happy with the skinning of the mesh and it fitted and moved correctly over the whole model. tweaking the envelopes took allot of time and was a pretty long winded process as I found many parts of the mesh which had not skinned properly and had to be modified with the envelopes.
buy using allot of tutorials I found that it was good to put the model in awkward positions that may be encountered in the finished animation. After a while you begin to deal with the irregularity's that pop up in the mesh buy just fiddling with the envelope properties and most can be fixed quite quickly.
