Wall Pattern Sheen

[JHuman]

I am working on a project where we are painting the walls a flat pain color then going back over it with a damask stencil that will have a sheen to it (semi-gloss). Does anyone know a way to do this?

Would I make a map of just the pattern and overlay it somehow?

I am using the most current version of VRay.
Thank you.

I'm not sure if I understand very good the effect that you want to achieve, but I guess you can use this method.

You should have two diffuse layer.
The first one with the mapping of the stencil on the diffuse color and the stencil alpha mapping on the transparency. This allow you to see the second diffuse layer only on the areas where you don't have the stencil.
The second layer should have only the color of the wall.

Now you need a reflection layer in order to add reflection only on the stencil.
Add a reflection layer with fresnel effect.
Add the same alpha of the stencil on the fresnel "Perpendicular color". You should have reflection only on the white area of the alpha mapping of the stencil.

Well, here is a render test and a diagram how I made the material.

Nice diagram!

One question: Why do you need to make 2 diffuse layers? Couldn't you just have a single diffuse layer with a mapping that contained both the wall color and stencil color?

Yes, but if you want to change the color of the wall, you will have to change the texture.

Sweeeet! Good ideas, I am going to give it a try when this rendering finishes up. Thanks for the tips, I will see if I can share the results when finished.
