to be more precise -> this lamp is like a juwel. it has a aluminium structure which holds blxk plexi-glas segments. some of the segments (more on the bottomside) are cut out to let the light shine through. the plexiglas itself is not transparent.

what I want is some light bulbs inside which light the scene - they should be visible when rendered. I need them to light the inside of the lampshade as bright as possible, allmost glowing like in real world and the light to emit through the holes and create visible rays like the sun shining through windows into a dark room with dirty air.

right now I dont get the inside lit like needed. in addition the light has influence on the outside of the lamp, which I dont understand, cause raytracing shadows is active and there is no other light source than from the inside..
