Normally in my scene, I use Lamp light(spot/hemi/point) there were no problems. ( no noise/fireflies)
But, when I switch to use Plane with Emission(Strength 100).
Noise and Fireflies start to happen here and there.
I have ticked Homogenouse in world setting. put Clamp indirect to 1.0. incresese the sample.... nothing seem to get rid of these noise.
Sample picture:: GPU Render , 300 samples.
Is there any way to reduce these noises and fireflies?
