Hi Dwanye @dillenbata3,
As I did more test renders, I am beginning to realize that the subject include portal or not is not as clear cut. And there are a lot more factors affecting the decision. And as you mentioned, in animation, noise, quality and render speed will need to be balanced carefully. There are much to consider and not just portal or not. The “max samples”, denoise etc will need to be considered too!
I will need more time to learn the interconnections of these parameters.
Thank you.🙂
