Twilight Render User Forum

I want to try a material that is similar to perforated brass. I think this can be done with png image, and probably a reflection image (so the metal reflects but not the holes)? There may have been some discussion of this here before.

thanks.
I should have tried a search on "perforated metal"

Thanks a lot. It was real easy making a png file in GIMP with a yellow color and clear holes. In SketchUp and Twilight I applied a perfect reflection template ("tile" )and turned the IOR up to four. Looks like brass screen. No need to add a reflection image. that was a rough test. I am making a certain light fixture so how light works with it is important. When I get something I like, I'll share.
