Houdini is a 3D animation application software developed by SideFX Software.

    Sketchfab currently supports static FBX files exported from Houdini.

    We don't yet support Houdini animations because it uses a point cache technique. Our team is currently working with SideFX Software to support animation and make the upload process easier.

    Go to File → Export → FBX and choose the options below:

    Export FBX options 3d animated model from Houdini for publishing on Sketchfab

    You can now upload this FBX to Sketchfab or compress it into a ZIP/RAR/7z archive to reduce the file size.
