Vray2Sided Mtl doesn't work with Multi/sub-Object

V-Ray V-Ray for 3ds Max Issues

Hi!
I found a ancient shader created with an old version of vray (1.50) but the shader doesn’t work properly. The character have a vray2sided Mtl, plugged in a multi sub-object for the ID, but the back material appears completely black.
If i apply the shader out of the multi sub-object, in a single vray2sided mtl, it’s works.
But i really need to keep the organisation with the multi sub, do you have a solution ?
Thanks for your attention.

Hi,

Which V-Ray version you are using now? I did a quick test with 3.20.03 and everything seem to work fine.

Would it be possible to you attach your file?

Ok, I get it, it’s because we use also a shell material with a shader viewport and a shader renderable. I test without this shell material and it’s works. It is strange because in the older version, it worked.

It seems to work fine here. Could you send us an example scene to support@chaosgroup.com or attached it here. Also which V-Ray version is that?

The version of vray is Vray 3.20.01

Thanks,
It must be something different, since I still can’t replicate the result from your screenshot using build 3.20.01.
Would it be possible to send us part of the scene to support@chaosgroup.com ?
You can also run a test with our latest official build 3.20.03.
