Improved CoronaVolume & CVolumeGrid

[JoachimArt]

I know I have mentioned this in other threads, because I thought it was a bug.
But now that I know its a limitation I would LOVE if this were on the list of improvements/features for the near future.

1. Being able to intersect different CoronaVolumes freely without artifacts and render errors. If you have two Corona volume objects and mix them together it should ideally just become more dense, right now it's uncertain what will happen, if you will see the bounding box edges or the mixed area becomes less dense or more. Its very unpredictable.

2. Being able to move cameras through CoronaVolumes and VolumeGrids without any issues.

Especially when doing animation and also to improve the artistic freedom when composing images (f.e : if you have a foggy room and want some extra dust in some few places or fly through clouds or whatever, this is a limitation that put a damper to the possibilities).

We are aware of these limitations (plus some more), and we will fix them as soon as possible. Unfortunately, it is not as simple as it sounds, and our developers always have a lot of work with other issues/features, so it will take some time.

Here is also a list of various known issues and limitations in Corona in general:

Thanks, I understand they aren't easy to fix. But I just wanted to cast in my vote on this. And I think it's an important feature because of three reasons: 1. Corona has the kinds of "it just works" reputation and overall experience, and in that regard it's a bit disappointing when such a fundamental feature needs workarounds and doesn't work as you'd expect. 2. CoronaVolume is awesome and can be used in SO many different scenarious. 3. And if it actually worked flawlessly it would give artists an amazing artistic freedom - expecially in a non physically realistic way....and Corona is increasingly being used for more than just Architectural visualizations.

I just noticed that you added fixing volume materials and volume grids to the Trello Roadmap. You guys are my heroes! Thank you for listening and planning to do this - this made my day! :)

PS! I just finished a project last week where camera and objects are flying through around 50 volume grid clouds, you can imagine what kind of tedious and boring work it was making sure neither the camera or any of the clouds ever collided :D

Many thanks for fixing this, much appreciated!
