More noise WITH Light-Portals?

by Jens Clar   Last Updated April 21, 2018 04:15 AM

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 ?
