Yeah... the bokeh.
And today i think needs a better background. Checking the thread about legos from Tiagomed
http://forum.corona-renderer.com/index.php/topic,3218.msg24103.html#msg24103 in the gallery learn some tricks on putting bokeh shape in Corona. Very Handy.
Also changed the material of "fireflies" from Coronaligthmaterial to corona with selfillumination, speedsup the render time.
I lowered the material emitter opacity to 10% or less and is better but now somehow misses against the background.
Today it didn look so right to me either. Happens all the time.
It seems better to do bokeh effect in post production, the render times drop down dramatically.
And Romullus, i didn't get it... XD.
Thanks for the advice!... most appreciatted!!!
