Ok I have tried googlig this one and I cant find anything, also I am not sure waht to search for.
I have been following a rendering tutorial from Digital Tutors and for some reason theirs works and mine doesn't.
I have a directional light through the windows and then a area light in front of window which does not emit light but emits photons.
As soon as I place the area light, it stops my directional light and doesn't work by lightign the entire room in a blotchy fashion like the tutorial video.
Even if I remove the area light the directional light doesnt work...
I tried messing around with soem settings but no luck.
If anyone can give me a pointer it would be much appreciated.
