Hello everyone.

I have created this set of boxes using this tutorial, It’s very computationally intensive because it’s creating a three dimensional grid of boxes ( 38,000 boxes in total ) which is bringing my computer down to it’s knees. I want to use something like Weaverbird’s Picture Frames to add detail to the model but I first need to cull boxes that are inside the façade, then I need cull every box face except for the façade.

I would appreciate any help, thanks in advance.
