control animation on ive or wrl files?

[Darkmax]

When i export my models with animation in wrl or ive files the animation runs in vizard in loop mode, how can i control that animation.

For example i want to play it when i want or pause the animation in some point, instead of running always the animation like crazy.

Just to clarify what im doing to have these animations:
When i use animations of translation, rotation or scale i just export in ive or wrl, but when i need to use animations of vertices, i use vrml(wrl) also or the osg sequence from tools that come with the osg exporter for max to exported in ive.
