Is there a VRay Fresnel texture/mask map?

[insanetk]

I am constructing a custom SSS shader with VRayBlend material, and to get a natural reflection on top of all those layers I want to use a 100% reflective material that is masked by a Fresnel mask that's exactly the same fresnel VRay uses, so that in render elements everything is virtually the same for the custom fresnel reflection and a inbuilt VRayMtl fresnel reflection.

I vaguely remember reading that VRay does have it's fresnel map available somewhere.

You can use the Falloff map; it's very similar.

Best regards,

Alright, thanks. It work's pretty well beside the difference that the raw reflection pass is affected by that falloff. It's not a problem since I won't comp with that. I think it would be great if there was a VRayFresnel map that acted 100% on the render elements internally.

VRayFresnelmap does not come to VRay3dsMax?
It is useful in order to be mimic of FresnelCurve based on IOR in VRayMtl.

In Max, the fallOff map always had the "IoR from shader" mode available.
The maya version is a nod to that one, i guess.

oops
I forgot IOR mode.
Thank you very much.
