I've learnt a lot to deal with 3D since project 1B. I've been using Maya integrated with MudBox to create models.
However, still there is a long way for me to get used to sculpting programs to make industrial products, not even close to master those programs. I'm glad to learn more and more! Moreover, my modelling skill in Maya is not good. I feel constraint from using Maya to create models, I prefer sculpting models.
