Hi all,
I'm experimenting with mediums and daylight environments to create fog/atmospheric perspective effects. I have some questions about the process:
1) Medium Radius: I'm guessing this is the sphere around the camera inside which ALL volume calculations will be made. What is the unit used here? If I'm using metric and the farthest object from camera is 1000 meters, should the radius be at least 1000 then?
2) Large scenes: In one of my experiments, I have a large scene with the farthest object (mountain peaks) being 8000 meters away from the camera. Understandably, the density needs to be very, very low for light to not be completely cut off. But I'm noticing that after a point, even if I decrement the density by one step (0.00018 to 0.00017), the volume effects just disappear. They were very visible at 0.00018, but completely gone in 0.00017. I'm not sure if this is a bug or limitation or a mistake on my part.
I'm including the link to my scene here if you'd like to explore it.
Here are other details about the scene. Let me know if you need to know anything more about this.
