This video will show you how to use the motion vector ROP. Then I will give a brief overview of the material setup in UE4. And then I'll go into some of the details regarding how we calculate a useful vector in texture space.
You can download the latest motion vector ROP from the development branch of our Game Development Toolset on GitHub.
