When camera moves far away,the spot light volumetric fog disappear.Anybody can help me?
What are you using to create the effect? Is it a mesh? If yes, then you need to create a custom LOD that causes the mesh to get larger when it’s further away. Otherwise, it will be culled out by default.
If this is not what you’re doing then we need more details before we can help.
Volumetric fog has a limited distance, it’s not meant for distant effects. If you want it to be visible from far away then you will need to use a different method to achieve the effect.
Increase the view distance in exponential height fog settings
