In this class, you will learn how to create a realistic-looking nebula in Blender.  If you ever dealt with nodes and volumes in Blender, you know how frustrating it can be.  Well, this course is trying to make that easier.  Throughout this course you will learn the best practices to create a really nice realistic looking nebula 100% in Blender.  At first, we will start by creating the basic shape of the Nebula, and then we’ll move to how to mold and shape it the way we want, using some clever technics.  Once we have a shape, we’re happy with, we’ll introduce more details to it, to make it look even better.  and to finish everything, we’ll also cover how to render and composite your nebula.  I want to help you untangle some complicated concepts in Blender, that people always assumed it is only for the elite of us to deal with math and vectors.  This course will be a nice exercise on certain aspects of blender, that most of the time gets neglected, or people simply assume it is really complicated, so they don’t bother learning.
