We exported an object with an animation as "dea" and imported in other application to use. Object's animation was movement animation. It worked great.
Then we changed animation type and made a modifier animation like surface subdivision. It worked in Blender. But when we exported the object exactly the same way with previous one.
There seems to be no animation in imported application. In previous one we could find name of the animation Blender gave but at modifier animation we even could not find the name of the animation.
There must be something we skip, I think.
