    Hello there again,
    I’ve animated 2 objects, first constrained to Path (and then tested with baked animation)
    One of them works nice, the other one seams to lose some keyframes or so : it stops for a while, then continue…
    See attached : one is whithin 3dsmax, other is within Verge3D.

    Are they both on separate paths that have been baked and the second one is just not working or is the white on a baked path and the yellow has constraints to follow?

    Hello,
    it would be the best if you could share the .max file.

    The torus (donut) seems to be using Path constraint? Which 3ds Max version do you use?
    NURBS surfaces and ‘Point curve’ are not supported, here are the supported path objects (green):

    I’ve first path-constrained a point helper, then bake the animation onto the 2 objects.
    They have their own keys, and are not linked to anything.

    When i tried to path contrain them (on 2 different paths), no animation was playing but the manual rotation keys i added. This is why i bake the animation from helper.

    Here is a simplified max file.

    1. Set keyframe tangents to linear for all baked animations, it should solve the problem.

    2.

    When i tried to path contrain them (on 2 different paths), no animation was playing but the manual rotation keys i added. This is why i bake the animation from helper.

    This issue occurs because the path constraint could not be exported (exporter cannot find the curve object). The messages in 3ds Max console:

    
V3D-WARNING: Can not export animation of Path Constraint for Point001
V3D-WARNING: Can not export animation of Path Constraint for Point002

    To solve it – simply convert your Freehand to Spline curve:

    The reason for this is the unusual structure of object. This is how it usually should look:

    Hope this helps

    It helped, many thanks !

    Indeed, collapsing edit spline onto freehand did the trick.

    PS : i did not tested the linear for the baked animation, as i did bake it every 50 frames to prevent too many keyframes, so linear would not work nicely.
    I guess it could work with an every-frame baking.
    Regards.

    A little tip:
    If the animation is long, instead of baking position and rotation, it is better to directly use Path constraint with animated “% Along Path”. It will at least save some memory.

    Yes, i was guessing that too, but as my path was not working, i tried baking it…
