Perforated mesh: how to move the metal sheet further away?

Hey,

I am using the perforated metal sheet example from http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&fork=hydra_1&id=Perforated_mesh but I want the metal sheet to be placed further away from the window.

So I modified the canvas to have the metal sheet 1 meter away from the window (I exaggerate the distance so you can better visualize it) and I scaled the surface x10 to be sure that the screen is covering the whole view when looking through the window.

Now the problem is that the generated image looks like this:

I would like to generate a similar picture where the metal sheet is also covering the sides… Do you know how to deal with that?

This is the modified canvas:
