Content and Task:
During this week, I need to rig the model of this character.
Since the model is not only asymmetrical but also has a high polycount, and the hole in the chest complicates weight painting, I will first use a plugin to reduce the polycount, retopologize the model, and remove the chest structure, replacing it with a flat surface.
Place the rig
Create cage(deform – cage – create) as a second low model for the low model. This allows the weights to be copied onto the lower module later.
Since the generated cage is too thick and overlaps around the fingers, I need to adjust its size. Then copy the weight of cage to our low modle.
Paint and adjust the weight:
Copy the weight in low model to the model with more ploygons, and adjust the weight.
Use blend shape to make the eyelid close
I encountered a serious issue: when sitting cross-legged, the thigh area stretches too much and twists, creating a very odd appearance. I need to switch from classic linear to dual quaternion and then use blend shape with smooth to adjust the shape of the model.
