The softwares i used are: 3dsmax, render engine Vray, after effects for post production, ableton for the sound track (original by me) and sony vegas for final editing.
It was not "that easy" to achieve the final product. I'm not any "3d genius" but i'm around 3d for 15 years as a professional since 3dsMax 3 and as an enthusiast for +20 years (back in the days of Commodore Amiga) .
There are some tricky bits like the assemble and disassemble of the models. Some are particle effects (3dsmax native PFlow) and some are also native MassFX that's a tool that uses dynamics to simulate breakable objects.
The best for me, and what takes more time, is the cinematography of the promo, like thinking of how the animation can evolve thinking of sound and dinamic movement at the same time.
The 8860 animation, i did on my spare time when i felt like it.
It did start just as a trainning session for some material technique tests.
It is not modeled very accurately as i started modeling some pieces by memory. I had this lego set and it always was my favorite toy.
The last pieces i went hunting for some fotos on the web, but nothing is modeled with real measures.
From that model I did 2 renders that actually are in the ChaosGroup (Vray render makers) gallery
