Hi All,

I have a box full of spheres and I'd like to make them transparent.

Looking at the documentation files on POVray, I used the command rgbft
specifying the filtering and the transmission of the light through the
object.

It works fine. However, when 2, 3 or more spheres are aligned (with the
camera position), they "overlap" and create a very dark region which kills
the whole effect of transparency of my spheres.

Does anyone know how to solve this problem ?

thanks

Dav

  (Btw, unrelated to the problem itself, but if you want to add a cool,
even though resource-killer effect, add "interior { ior 1.5 }" to the
spheres... :) )

Then add some dispersion:
interior{ior 1.5 dispersion 1.05}

that works !! it definitly was the max_trace_level that has to be
increased...
Cheers

I've tried this effect..but it sort of make the whole thing a bit messy.
