Xrel -- I noticed that the textures do not shrink along with the size of the box's when hit by the laser. That can be fixed by adding a little something to the textureMatrix. Here is a standard textureMatrix = [1.0, 0.0, 0.5, 0.0, 1.0, 0.5, 0.0, 0.0, 1.0]. If you add two simple calculations, then the size of the texture will increase or decrease with the size of the box. You need to modify elements 0 and 4 of the textureMatrix array like this:

textureMatrix = {[1/size(0), 0.0, 0.5, 0.0, 1/size(1), 0.5, 0.0, 0.0, 1.0]}

Make sure to include the beginning and ending squiggly brackets as shown here.

This can also be done with circles but it's slightly different because a circle size is determined by its radius. So it will look like this:

textureMatrix = {[1/radius, 0.0, 0.5, 0.0, 1/radius, 0.5, 0.0, 0.0, 1.0]}
