VRay2Sided and double sided option in VRayMaterial strange behaviour

[Jiri.Matys]

Hi,

I found this strange behaviour:

I have 2Sided material with default values and VRayMaterial as frontMtl. Make a scene, put sun as back light, but leaf is not translucent. I disable "double sided" in VRay Material and everything works perfectly. Nothing else (as far as I tested) has any efect on translucency. But I dont remember I had to do this some time ago.

Now I test in max 2016 and newest VRay, so maybe some change in this? Or is it bug or normal?
I even try some time ago buyed trees from Archmodels and leafes are not translucent until change double sided check box. I think its strange.

In the 2-sided material, there is an option "Force single-sided sub-materials". Is this enabled or not?

Best regards,
Vlado

It doesnt matter, still the same. But I found, its happening only with Laubwerk Plants, but dont know why. Even dont need to apply 2sided material at all. Leaves are translucent only when I disable Double sided in that VRayMaterial. Its really strange.

Hello,

Can you post sample scene containing some of the Laubwerk Plants models in it for some testing?
