The effects were applied to the tree at the strand level. I didn't realise that effects done at the strand level wouldn't go across with the xml data file sorry.
To get the two light sabers to come down I used a curtain effect set on close and curtain edge left. For them to go back up it is curtain effect open (at tleast that's how it works on my tree model).
To get the lights to move left and right, I applied short bits of the ON effect to the other strands to make it look like they move left and right and when they contact eachother, I used a red and white or green and white On effect with shimmer ticked.
I will take a screen shot when I can and post it up.
