Just discovered that twinmotion is free to use (with a 2k export limitation) and runs surprisingly well on a modest PC. Possibilities seem endless, from the huge high-quality model and texture library to terrain sculpting and real-time rendering, and very quick image export. There's only one catch, no sweethome3d plugin.

So every time you need to modify the original model in a more specific way, you would also have to start the twinmotion project all over again, pretty much. For other 3D software there are plugins with a sync option.

Some people here managed to produce more atmospheric renderings with sweethome3d, but i never quite got the hang of it. So i got a bit carried away the first time playing with proper textures, with blemishes and wethering signs and all.
