Please, some pointers. Customising particular bricks materials?

Hi!

I've just set up LDD to POV Ray, and I'm amazed at the results. Right away I wanted to get some customisation going.

I downloaded a light-sabre model, and it looks great, sadly the light beam is dark green. I'd like to add emissive properties to the bar of little discs making the beam.

I checked the POV file and the materials are complex - lots of arrays.

I did discover the lines of the beam - the clue was there was lots of them, ldd_6143. I'm stuck now - how on earth do I customise ldd_6143 to get a gorgeous emissive green glow?

I've found the ldd_finishes.inc, and all_part_materials.inc file...... but I'm stuck.

ldd_6143(array[1]{28},array[1]{0},array[1][12]{{0,-1,0,-1,0,0,0,0,-1,20.850440979003906,2.8000795841217041,-0.40000170469284058}})
ldd_6143(array[1]{28},array[1]{0},array[1][12]{{0,-1,0,-1,0,0,0,0,-1,21.810440063476562,2.8000795841217041,-0.4000018835067749}})
ldd_6143(array[1]{28},array[1]{0},array[1][12]{{0,-1,0,-1,0,0,0,0,-1,22.770439147949219,2.8000795841217041,-0.40000176429748535}})

Could someone please help?
