What with the new renderer in Vue 5, Have they fixed the bug that makes invisible objects partially visible in volumetric light?

Yes, this bug should be fixed.

I do confirm, this bug has been fixed. While testing this bug came along in several scenes and E-On was able to kill the bug. Haven't seen it anymore since that happened.

W00t! That bug kept me from using Vue for several scenes in my movie, I'm so glad to hear it's gone.

Besides, it was not a bug. It was a behaviour that was inherent to the way the old Vue rendered managed the rendering of the scenes. More precisely, it was part of the price to pay for the relatively low rendering times of the old engine. I specify this because there is this legend of Vue bugs never listened to. This is one of those legends. I got the above answer (in more appropriate technical language) from a person very high in the E-On's hierarchy (won't name him/her sorry), and I got it not much later than Vue 4 was launched, this means at least two if not even three years ago.

Its a bug in an artist's eye, so... The star network render bug still exists so I guess there is always some truth to legends. : - )

Orio - I got the same explanation from someone at e-on's as well. It makes sense that it was not considered as a bug but as a price to pay for the tradeoff between quality and speed. The problem was that in reality, it did reduce greatly the usefulness of volumetric light, especially with characters (hair, eyelashes, transmapped clothes...). I am glad to see they found a solution to this problem eventually. It is good to see these things get sorted out after a while (like the infamous blue gunk :) ).

You don't know how many times I begged them about the blue gunk ;-)
