Hi Roy,
I tried this out and turning off ‘Seen by transparency’ on the HRDI sphere seems to solve the problem.

I basically made one hole inside a square using splines and extrusion. I used the Falloff shader in the Luminance channel to get the ‘depth’ pass. I used this render in the alpha and displacement channels to create the grid in the image.
This can also be achieved just using gradients too I think.

This setup is not working as the Random Effector is just randomizing the visibility of the clones… So the clones out side the fall off are not randomized and hence are visible.
This is my solution:
Use a Plain Effector instead of the Random Effector with the same falloff and the visibility box checked.
In the Effector tab of the Plain Effector, Change Max to -100 and Min to 100.
You will see that the clones in within the falloff disappear. Invert the falloff.
Then apply a Random Effector.
Uncheck everything in the Parameter and increase the weight transform to 100.
Create a box fall off just big enough to contain the other falloff.
Invert the falloff.This should sort you out.

Hi Craig,
This is what I achieved using an alpha map and displacement. What I did was to create a single grid cell using the extrude method and render it out. Then I used that image in the alpha and displacement channels, and then tiled it on to my model.
Tried using a normal map to get the bevel, but it was not working.
The mapping is a bit off and the displacement gets a bit crappy if you look closer, but it does a pretty good job I think.

Hi,
With wide shots the alpha solution works well. I am not sure if it would work very well with closeups.
This is how I would do it:
Take a circle spline, clone it using a grid array into the desired grid you want.
Then collapse the cloner object to get the splines (you will get a null object with all the splines as children). Now if the initial circle was a parametric object, you will have to select all the circles and convert them into splines as well.
Then with all the splines selected, do connect+delete.
You will get one single gird of circles spline.
Now if you want a rectangular grid, draw a rectangle around the grid of circles.
Make the rectangle editable (if not already).
Connect the grid and rectangle together.
Apply a Extrude Nurbs modifier.Now this solution gives you real geometry. You can also bevel the edges of the circle grid easily.

You can do this in Particular as well, using your matted footage as a layer emitter. You can emit particles from this layer and add wind and turbulence effects. Could get close to the kind of effect you are looking at.
