I've been all day working with the corrective shapekeys. I've understood how they works : I need to modify the mesh manually with the proportional editing and then I should create a shapekey with the mesh modified correctly,BUT what I'm not able to do is to fix the legs of my character,because they became very damaged after that I have imported a BVH file. I tried to modify them with the proportional editing tool,but the job done is not good,since its difficult to alter carefully the mesh,especially behind the knee. Any suggestion ? Is there a way to fix it decently ? thanks. image attached.
