Particals folowing a curve

Hi,

Is there a way to get particles to follow a curve in blend 4 web? I have set them up in blender render and switched over to b4w and they work in blender. I have even tried baking them, but they still flow in a straight line when i export them.

Is there some setting I am missing? Or is it following a curve not possible in b4w.

Thanks

Or is it following a curve not possible in b4w.

Unfortunately any manipulations with particles except influece of gravity and wind are not supported.
