Global Volume not working properly in Corona 7 and 8
Misha_80:
Global Volume not working properly in Corona 7 and 8 .
See attached picture.
First pict "box volume" . Volume mat attached to BOX . Working properly.
Second pict "global volume" . Volume mat attached to Global volume in settings . NOT Working properly . No "fade out". All figures look equally .
In both case material the same of course.
This bug appeared in Corona 7. 6 -work normal.

Ha! So it's not just me who paid attention to this :)

What you are seeing here is expected.
When you are using a box, it is basically surrounded by light which passes only a small distance through the volume. That's why it's brighter overall, and in turn makes the fog effect easier to see when it is in front of other objects.
When you are using global override, the fog is taking much larger volume (it is like using a HUGE box) and the lighting is evaluated based on the environment distance ("enviro distance" in development/experimental stuff rollout - https://support.chaos.com/hc/en-us/articles/4528469959953).
If you make the box object bigger OR if you lower the enviro distance value, you should get similar results.
Also there is a difference between rendering global volume between Corona 6 and 7 and the explanation is:
This is a result of a fix we did. Previously the global volume was around the whole scene geometry up to "enviro distance" from it. This means that removing/adding geometry changed the global volume. Now it is around camera up to "enviro distance" from it.
So to me, everything appears to be working as expected, and if there are some differences compared to Corona 6 - that's a result of fixing something that was not working correctly.

What can say here? - It's terrible :)
It now looks as if a turbid glass was placed in front of the camera. Therefore can probably forget about Global Volume.
Then it's better to use ZDepth pass and further in Photoshop...

It's not a matter of what is terrible or awesome, but what is correct or incorrect, as most things in Corona.
You can try lowering or increasing the "enviro distance" in the development/experimental stuff rollout that I mentioned in my previous post. It should be able to get results similar to pre-V7 versions of Corona this way.
