Some interesting light effect renders.. I was just experimenting with the lights I created for the inside of the buildings while twquicking them and seem to have effected the external of the scene as well, but in a positive way. I think i managed this while using final gather in the render setting of mental ray.
Really happy with these renders even though accidental.. but then again accidents happen sometimes when u least expect them and you end up creating something incredibly beautiful..!!
Slight change on the arches lighting on top left building.
Adding a point light..wow too bright
I waned to try and experiment by adding a point light in the actual street lights and animate the glow but due to the fact I already had a material assigned on the faces (mia x) which originaly gave it a with glow but at the same time it a material that would bounce off light cause of being reflective like glass or a mirror.
