Opacity Map problem with vray material

[wreath]

Any help? still suffering from it :sad:

I've never used Vray, but the Gradient Ramp is probably not supported by Vray since it's a Max procedural texture. (I assume the other procedural maps like wood are unsupported as well?).

Use a plain texture instead, that should work. :thumbsup:

[wreath]

It's too bad, can you advice any other way to get same result?

[Marcel]

How are you mapping the Gradient Ramp? You can always use a second UV channel and a texture instead. If you really like the look of Gradient Ramp render it out to a texture :)

(I assume the other procedural maps like wood are unsupported as well?).You are wrong here; V-Ray supports all the standard 3ds Max procedural textures (the material *is* transparent where it should be, after all).

To resolve the issue, you need to un-lock the Fresnel IOR of the material from the Refraction IOR, and adjust the Fresnel IOR as you need, instead.

This is because, when you enable opacity mapping, the material is assumed to have refractive IOR of 1.0, and the Fresnel formula gives zero reflection for IOR 1.0.

Vlado YOU ARE THE MAN! :thumbsup: thanks so much:bounce:
