So I have a bunch of lights inside a box with a transparent front (I tried to imitate perspex).
Most of the lights are working fine (they are all done the same way, I just duplicated everything.
The last column of lights on the right hand side seem not to work (but if I put them outside the box they are working fine). So I guess it's limit on rays going through the transparent object? I have no idea what setting to adjust to fix this.... Any help appreciated!
