When i use volume scatter on world, its all pitch black.
Its works fine on a new blend file, and if i append all my objects.
But as soon i save the file, and reopen it, its all black again.
what is happening ?
Are you using a world environment texture https://cgcookie.com/blender/lessons/cycles-volumetrics-world/
No im not using any environment texture.
I followed tutorial on blender guru.
The funny thing is, if i make a new blend file it all works great. I append all my objects to that file, and it still works.
But if i then save the file and reopen it, its all black again.
Supply blend file
