Reflections on a wire fence

[Tobobo]

This might not be possible, but I want to create a fence texture for a wire fence with reflections. I have a lot of fencing to model so I want to use a flat face with textures.

I can get the transparencies right so only the wire sections render but I want only the wire surface to have reflections.

But when I add the reflection layer it doesn't follow the alpha channel and puts a reflection across the whole face the texture is applied to.

The image below is a test. the back ground is red to make sure the transparencies are working.

the one on the right is with out reflection and the left has Fresnel reflection applied.

Any ideas?

I think your best bet would be to use a reflective metallic material (ie Chrome) and then use your fence texture (black and white version) as a diffuse mask on top. That way only the area that the fence texture shows will be reflective.

That's a good idea Rob, I'll try it

Thanks

I'm no help on this but your subject would make a perfect title for some banal modern art piece.

Just a small detail - you need to make sure you put your alpha mask at the "perpendicular" material in the fresnel reflections. Otherwise, you will have a reflection over the whole face. With the diffuse mask, only the diffuse layer will be transparent.

You could also try a normal map or bump map to try and get the reflections going in different directions on the wire.

thanks Andy, I'll have a look into that.

EDIT

Andy,

That worked a treat!!!!
