Hi all, I have rendered nighttime versions of the bridge scene and experimented with lights for the first time. learned a lot of things. Tried initially to put the lights inside the lamps where the bulb was, but to no effects, no light came out, blocked by the model even with those parts being transparent glass. Then redid the model with no glass but simply open areas, light came out but the shadows from the frame blocked so much that this was not valid. Tried invisible lights in the middle of the space between the lights, bulbs luminous, great lighting but the reflections in the water were not realistic. The option that seemed to work best was individual lights for each bulb, placed on each bulb and subsequently moved outside the lamp object in line with the camera axis of view, very close to the lamp object, lights all invisible, but the bulbs luminous. Played with the atmospheric light settings. The results are below, first the failure, second the relative success. The bridge was the one before the water line and the floating rock fix. Sorry !
