This is my low poly
Here a shot
Don't look hands, i'm finishing it these days. I would like to understand one thing, making me crazy. I'm trying to check if my low poly was made well for animation (topology of vertices, the shape of muscles in particular the back the shoulders and the chest/pectorals)
Now it seems working all pretty well except one thing: PECTORALS and AREAS NEAR THEM
Here the situation
If i move my upper arms down the deformation is this one
Now it isn't so impressive but the mesh of chest goes inside the shoulder in point 1 and in point 2 it deforms inside the body. I have tried weight paint but i don't think it's the definitive solution. I have doubts for my mesh and vertices.
Now my question is:
1)Is a problem of topology? (i have followed a very useful tutorial for doing that in particular this picture) Too few vertices? I think 5800 for a low poly was too much^^
2)Is a problem of my mesh: did i make pectorals too bad, too large or something near the chest isn't right?
Can someone help me??
