you are a GOD Johny....thanks so in order for lightportal to work is to have that illuminated sphere? because when i delete it, it crashes. thanks again.

Yes You need Lumi ball outside and PHOTONMAP mode in PHOTONS TAB + skyportal for Lumi ball and Sun (if you need correct GI inside) .
Skyportals are very usefull in rooms with small windows becouse Skyportals make correct photon map for Final Gathering.
