Normals issue

V-Ray V-Ray for 3ds Max Issues
1

I’ve found a strange behaviour in VRay 2.00.02 regarding to normals:

1) Create a box
2) Apply a Normal->Flip modifier
3) Apply a VRayMtl
4) Render

It seems that VRay ignores the flip normal, but it works fine using a Standard Material. What am i missing ?

I do not know about Vray 2 but on 1.5:

Pull Render Setup rollout \Global switches\Force back face culling.

i think vray default to force the material to be a double sided, its in the vray material options.

Solved. Thanks for replies !
