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.

For more info about motion vectors and creating a UE4 material check out Klemen Lozar's awesome tutorial - Frame Blending with Motion Vectors

    Hi mike, I followed this tutorial exactly and all i am getting is the entire frame of each image running up and to the left with no distortion. Any suggestions?

    Does the motion vector texture look correct?
    Have you turned on double apply motion vectors in the material instance?
    Does your number of Columns and Rows value in the material instance match your texture?

    Thank you for a wonderful tool.
    I have a question.
    If I turn on double apply motion vectors in Material,
    Emission and Alfa flip correctly, and the motion vector continues to flip to the upper left.
    If I turn off Double Apply Motion Vectors in Instance Material,
    The Motion Vector flips correctly, Emission and Alfa continue to flip to the upper left.
    How can I flip Emission and Alfa and motion vector all in the same way?

    Can you check the FlipBook_MotionVectors material function to make sure that the ConstantBiasScale in the Motion Vector Setup section has Bias = -0.5 and Scale = 2.0

    Thank you for your reply.
    I could solve it as I had you taught me.
    I appreciate you very much.
    Please keep making great tools in the future.
