Learn how to generate VAT Characters where you define the character motion without using bones and skeleton meshes. The animation comes from textures, using the vertex animation textures method. Then learn how to add variation to your characters when they are placed in the level.

Project Titan is an in-house tech demo designed to production test Houdini's procedural workflows while creating a 3D environment that leverages the latest technologies in Unreal. Click Here to learn more.

    ive been looking forward to this one the most. thank you (:

    I would suggest to use not Random from Pos, but instanced mesh with Random Per Instance. This will let you to keep the same character look when it's move.
    Also please be aware you can have a problems with the float point precision in vertex/pixes interpolation. So it's better to separate by UV tiling instead of the bitmask.
    We had a pretty similar tech here, with 10K crowd and different weapons: https://youtu.be/4NEUPQzH0D0

    How come I dont get that information when I hook up a null to my fbximport. Around time 8:00 min?

    This is great

    how do you get the textures map to come over with a character. In my example my character has uv and textures that look great in Houdini but inside UE5 the textures dont look correct. Like the UV are screwed up. The animations are fine but its the textures that are not correct.

    Very interesting. I love this kind of article.

    I have three questions.

    1. Making character variation by shader trick can be achieved with regular bone animation model too.
    What is benefit of using VAT animation in this case. e.g. Low cpu usage?

    2. Can these vat characters be instanced in UE scene?

    3. Did you use any tools or techniques for making the multi parts character model? It seem to be a little difficult for non technical artist.
