- Because 25 ray bounces in my opinion is to much for this scene.
Why? Do you even know what it does? What is the difference in comparison to default?
I don´t have use portals.
You should. It shouldn't give you any visual difference but should speed up your rendering about 3-5 times. :)
Yes, I know. It´s about light bounces.
I had already tested these parameters, and therefore decided not to use portals, I knew that HD cache it´s faster, but it depends on the quality I seek also, so I decided to use PT + PT. Here are the pictures of the comparison.
But I appreciate the tips, it is always good to try new possibilities.
