Ok. Then the fake one will be quite simple.
Although RC is powerful in computing keep in mind that manipulating with pre-prepared model components is much faster. For instance, the present Macro is based on calculations on how each segment will be placed/rotated so it could take some time to generate if you are working on a large scale scene.
On the other hand, if you use pre-prepared segments and just use randomize/sequence/compose operators etc, RC will use the benefit of instancing and everything will be much faster and memory-efficient because generating will be based on simple "segment-stacking".
