Ability to disable alpha contribution for CoronaVolumeMtl

[pokoy]

It looks like using a CoronaVolumeMtl will also affect alpha channel, there's no way to disable it and it can get problematic when used and global volume material... Could we get a checkbox to disable alpha contribution in this material?

EDIT: Also, using a CoronaMtl as global volume material will also affect alpha in exactly the same way, even when alpha mode is set to black. Not sure if to post this as a bug since this should not happen...?

Or maybe we could have a checkbox to 'ignore volumetric materials' in the alpha element...? That would be the most elegant solution I guess.

I tried to play with this and I am always getting zero contribution of volumetrics in alpha channel... can you share a simple scene demonstrating the problem?

Will have to dig out the specific scene, could take a while unfortunately. I can't recall the situation that led to the request so will have to test, sorry...

ok, I will close this down as part of the spring cleaning, feel free to reopen if you find a problem again

Just found the project. Will send an image via Skype for you to look at.
