You would NEVER model metal mesh.
This is usually simulated with a vector grid fill for analytical views, a bitmap image for OpenGL and a LightWorks shader for LightWorks rendering.
Resize the 4x4" grid fill and save as.... for your new mesh. Be sure to use vector fills view method to see it.
For OpenGL, find an image or draw one in Photoshop with alpha masking for the mesh voids, and for LightWorks, use the LightWorks shader : Transparency>Wrapped Grid.
You can also make this mesh in LightWorks, render it on a flat, evenly lit surface and capture the image to use as your texture map for OpenGL.
Do you have photoshop to create the alpha mask for transparency?
