While using the "Volume Scatter" option in Blender the Background turns Black. (I am using Blender 2.79). Here is my issue in detail.
The first image below shows a normal scene with Blue sky (Set using the "World" as shown in the image)
I wanted to add mist to the scene; so i used the Volume Scatter shader and plugged it into the "Volume" node in the "World Output". The entire scene turned black and later I discovered this feature doesn't work with the "Sun Lamp" well. So I added a "Point Lamp" too in the scene. Now the mist appears. But the issue is that the blue background has entirely turned into black as shown in the image below.
I've tried changing the Strength of the "Point Lamp" but it won't help. I would request to kindly inform if anyone knows how to fix this.
