ZBrush 4R8 has an amazing new feature called VDM or Vector Displacement Mapping. In this 30 minute video I look at what VDM is and why it is such an important new feature for us digital sculptors. The key is understanding the role that alphas have played in the brush system up untill this point. Alphas, in simple terms, are an efficiency. An efficiency that comes at the cost of specific real world sculpting behaviors. They are cheaper, computationally, than adding in actual pieces of geometry. A
