Picture shows one way using HOLLOW sphere with holes cut in truespace and exported as dxf (bryce will fill holes if not dxf). I haven't tried with holes cut by bryce. Just rember that sphere must be hollow or light will have to fight through sphere material (1 positive sphere + 1 negitive sphere scaled on x,y,z smaller than first(differance in volume is walll thickness) and grouped together. Another way to fake it is; Use paralelle lights grouped like cross duplicated and rotated until density is correct then grouped again and rotated on y axis (to form a complex spiked object) then regroup with the light settings set to surface visable and infinate. I'm not sure that the effect will be alll you want but it may halp.. Good Luck! td
