Refractive Material Alpha bug?

[ben_hamburg]

Hi,

I just stumbled upon a problem and I´m not sure if that already existed pre- Vray 3.0

Example:

-Make a box, assign a solid material.
-make a teapot, put it in front of the box, assign a refractive material
-In the refractive options enable "affect Color+Aloha" or "affect all channels".

The alpha of the teapot will now be grey, so that you can´t switch out the image background in PS, because it will also show through the solid box behind the teapot..
Shouldn´t the alpha be opaque where the solid box is visible behind the teapot?
Is that a normal behaviour or a bug in 3.0?

We have a similar issue into our system but I am not sure if it is the same one.
I also tried to reproduce this issue but it seams that it works fine in our environment.
Would it be possible to send us a sample scene and let us know which is the exact version of Vray that you are using?

Thank you very much in advance.

I am having the exact same issue!

Has that been resolved yet? My Vray version is 3.00.04.

Is it possible that this is a bug triggered by unticking the 'affect alpha' option for the Vray domelight?

I can't seeem to find another explanation. This is really weird.

I have installed the latest Vray version now and the problem persists.

Would it be possible to send a reproducible scene for investigation?
Thank you very much in advance.

I actually sent a small scene to the support team this morning.

Ticket No is #557991.

Ooops, problem solved.

I accidently had the reflection affect color and alpha.

Too much work and not enough sleep
