# Creating big number of arrary in blender

I am trying to make visual comparison of money stacked upon each other in group of 100 notes(bills).

In screen shot, small stack on left is \$100 and on right it is \$1 million which i created through array modifier.

The problem is i have to make it till billions and already, my system is running out of memory.

Please suggest me a good technique for it (give bit details as i am newbie). Thanks

• Why are you using real, individual notes meshes? It will be memory intensive, and in your case it's also a waste of resources because the notes show no variation. It looks artificial. I'd introduce some variations to the notes (rotation, creases, etc) then I'd use microdisplacement on a cube of the size of the desired stack. I'm working on something similar, a chain mail texture made from individual chain links. I'll update my question later today, it might give you some ideas on how approach your issue. – Rhaenys Aug 26 '17 at 15:27
• I concur with @Nihal, an old rule for 3d is not to waste resources in what is not visible. What you need is very simple geometry and even cleverer texturing. – user1853 Aug 26 '17 at 15:37
• as i have told i am a beginner, i don't know much of this stuff nihal is talking about but what i have works with me. I want to keep it less complicated (as much as i can) – Eirtaza Aug 26 '17 at 15:59
• If you are really going the single objects road, then use instances instead, or perhaps particle system, and benefit from memory optimization, otherwise it will quickly become unpractical. – Duarte Farrajota Ramos Aug 27 '17 at 0:03
