Telescopic bone setting:
I used to drive the model of the two bones in the video teaching,analog pectoral muscle deformation,in practical applications,You can add a few more,their direction are concentrated point to a virtual point,bone can be a little thin,so that the vertex of the skin when the model will be the mixing of multiple bone,the deformation effect will be more gentle.The ribs can also increase the number,make the model more realistic deformation effects.
17:32 Additional skeletal applications Look at Constraint,must pay attention to change their Upnode to as small as possible bone changes with the angle between them.If Upnode default World,bone to maintain in a world coordinate system axial angle;if Upnode choose the larger bones with changes in the angle between them,may produce a sudden rotation.
22:37 Create a few bones as the clavicle,order for them to affect the surrounding vertices,producea relatively small deformation zone.
32:24 Biped skeleton shoulder blade design,deformation of the shoulder blade for the back muscles are very large,especially practiced fit people,scapula to the sink can make the back appear to be more broad.If there is no shoulder blades,to make a Bruce Lee in 'Dragon' of the duel in the arena before the warm-up lens is not possible.Therefore,when assembling the skeleton of the realistic characters,I will give them plus two shoulder blades.
Due to my poor english that pls refer to the subtitle for your convenience.
