VrayBlend and Fog Color

[zakos]

hi there !

first, i'm sorry for my really bad english, so i expose my problem with some image.

i build two simple glass shader and addon some color in the fog :



now i place this shader in a standard Blend material with a bitmap mask : the result is good



But if i place this shader and bitmap mask in a VRAYBLEND material the result is wrong :



i have not trouble with a simple shader with different diffuse, this append only when it is a glass with fog color

When you use a VRayBlendMtl material, the fog is taken only from the base material.

Question: Could you not achieve the same result by mixing two colours with your bitmap as a mask (in a composite map) and input this in the fog colour slot of the refractive material instead of blending two materials. Since the only difference between the two mats is the colour of the fog, it would seem simpler and may be faster to render...

It would work if the fog color was mappable, which it currently isn't. This is implemented for the next service pack though.

Thats something I've wanted for quite some time. Any idea when that service pack would be released?
