Good day!

I would love to have a fog in my project, but I couldn't make it happen, because my project has a giant island which I want to make all foggy, but Volume Scattering seems to not work normally when the scales of stuff is really big.

Maybe it is a bug...

I hope Blender will treat 1mm objects the same as 1.000.000km objects one day...

  • Let's put it in another way. Are you going to see object of 1mm and 1km in the same way while in the heavy fog ? Also - 1 million km ? Well, Blender will treat it as usual, your hardware won't. – Mr Zak Mar 19 '17 at 10:02

    My system handles millions of km well but various artifacts arise when the sizes are too small or too big. I mean it could be like in vector graphics. Everything stays the same no matter the size.

    Now I can't use the cool volume scattering feature just because everything in my scene is very large.. Yes, I could remake everything into smaller scale but I would need to redo all the animations and I still would not be sure if Volumetrics is going to work fine...

    You can test it yourself. Create a new empty project ->add World Volume Scattering->add a light source->tweak all the parameters so everything's working okay-> and scale up high the same setup and try to tweak the parameters again and it's not working anymore... When I adjust the Density of Volume Scatter I can only get totally black result or totally fog-absent result... – Ignac Mar 19 '17 at 10:17
  • As I said, your hardware will not (more than likely). The artifacts you see on big objects are caused by cliiping flicker which will happen in any case on big objects, and that's the end of precision by graphic card. Millions of kilometers ? Maybe it's possible to handle that, but.. why ? – Mr Zak Mar 19 '17 at 10:44
