Extremely grainy render I am trying to create an under water scene but it is not turning out like the tutorial I am following. My main issue is when I come to rendering the image it is extremely grainy and I cant get it to look realistic. Would someone be able to help me with this problem and explain in really basic terms as I have no other experience with these kind of projects. Thanks in advance!
Its a viewport render preview at 32 samples.
No wonder its grainy.
Increase the samples.
With glass materials try at least 1000.
