Twin Motion has just been bought by Epic Games, and – somewhat unbelievably – they’re giving away the current version for free until November. Apart from few minor tweaks, this is the full version of the app which usually cost about $1,800, and you own it in perpetuity. You just need to sign up to Epic Games and download the launcher. No catch, no fees. It loads C4D files natively and runs on both Mac and Windows.

I grabbed it and it’s great fun!
