Vray Blend material and additive mode

[Gecko]

Hello , maybe this have been brought up before but i haven ' t seen post about it :
If i use a Blend material with additive mode , and plug that material into another Blender , the last blender will behave as if addtivie mode was toggled on.
Or is there another way to blend the materials and keep the additive mode in one of the shading branches?

Regards,

Gecko

Hi,
I know this bug. It looks like this bug : http://www.chaosgroup.com/forums/vbu...light=additive
I think it is "normal" because the additive mode is a "hack".
Now i know i must never use the additive mode.

I'd like to inquire whether something has changed about the way additive mode works in recent version of Vray -- I am re-rendering a scene where I used additive mode in a blend shader to create a glossy coating over a SSS shader which previously rendered correctly, although with a different lighting set up. I'm now rendering this scene again and color is not always passing through the added layer properly.
