I'm attempting to set up an underwater scene in Cycles by using the world shaders. My node setup isn't very complicated, it's just a principled volume node with the usual background node.The problem is that any density value above 0 completely blackens the whole scene. I want my scene to have an atmospheric look but still allows light to pass through. This is the scene with density set to 0:
And this is the scene with .001 density:
I'm not sure what the issue is. I have a pretty strong sun light source in the scene, and this has never been a problem for me before. Any advice would be appreciated.
