Reply To: rendering problem with the cube volume
Hi Adrian, you have already figured it out by yourself!
When you set the Viewport Display of the Cube to Textured or Solid, the Environment (light) can’t enter the Volume (Cube), so from camera view you can only see what is inside the Cube (because the camera itself is inside the Cube).
When actually rendered (with F12, not the Viewport Rendered View), This will be a problem, because then the Cube will also block out the Environment.
What you will need to do is remove the connection between the Colorramp and the Surface of the Material Output (I don’t know what that’s doing there…), like so:
That should fix it.
