I used Light portals for the first time in my last scene, and after the difference was nearly non existent i made a test scene.
Everythign is laid out to produce as much noise as possible.
In this test-scene an activated portal produces MORE Noise at the same sample-count.
What is happening ?
I thought Light-portals were a good thing ?
I knew they have diminishing returns and slow down each sample. But shoulndt they always produce less noise with the same sample count ?
